Add crash report to createdump for Linux Watson
For Linux Watson the crash report will contains the .NET Core version, the faulting process name (the module/assembly containing Main) and the managed exception info (including the exception HRESULT) and thread stack trace of the thread the caused the crash.
Add the CLRDATA_MODULE_IS_MAIN_MODULE flag to the DAC's IXCLRDataModule::GetFlags API.
Add code to get the managed method name and write it out as "method_name" (even on MacOS).
Add native frame symbolization (unmanaged_name) using dladdr.
Only get the image info once and save in a global
Demangle the stack frame symbols
Only write PH_HDR_CANARY section if neccessary

Add crash report file for VS4Mac Watson
Add the --crashreport createdump command line option to enable this feature.
Add crash thread (--crashthread) and signal number (--signal) command line options. Use std::vector for g_argCreateDump.
Add the COMPlus_EnableCrashReport environment variable to enable this feature.
Add simple json writer (JsonWriter).
Remote unwinder: special case when encoding == 0 and IP after syscall opcode to popping return address
Remove unwinder: add functionStart return from remote unwind API
Add ModuleInfo struct containing the info about a native or managed module.
Add StackFrame struct containing the info about a native or managed stack frame.
Add signal number to PROCAbort.
Currently the Linux crash report is stubbed out (empty).
Better createdump logging.
Add CrashReportWriter class.

* Fix PAL_JitWriteProtect export on Linux
I have not realized that we actually export that symbol on Linux too and
that mscordac then have the dummy function missing.
* Code review feedback
* Disable PAL_JitWriteEnable usage in DBI / DAC

* Unify macOS ARM64 write protection holders with W^X ones
This change removes the original holders that were added for changing
memory protection for executable code and moves the actual switching to
the recently added W^X holders.
The unixexports files don't support target specific symbols. So I needed
to export a dummy version of the PAL_JitWriteProtect for macOS x64.

Generate coredumps on signals
On MacOS, coredumps are generated if there is an unhandled managed exception
but signals don't generate them.
Enable a stripped down version of the Linux signal handlers for MacOS.
Add a SIGABRT handler so calls to abort() in other native code causes dump to be generated.
Add COMPlus_EnableDumpOnSigTerm that enables dump generation on SIGTERM.
Moved the "generate dump on SIGTERM" logic out of the PAL into runtime's
HandleTerminationRequest callback and passed a new SCA enum down to
SafeExitProcess that calls TerminateProcess instead of ExitProcess
which generates a core dump.

shadow stacks (#51887)
* Add an implementation of `RestoreContext` for Windows/amd64 for use with shadow stacks
- Added `ClrRestoreNonvolatileContext` to Windows/amd64 similar to the PAL's `RtlRestoreContext` but allowing for example continuing from exception in managed code when shadow stacks are enabled
- Updated to use the new implementation for cases that don't need the volatile register state restored. The two remaining cases that still use `RtlRestoreContext` would have to be changed later to use a different mechanism.
- For other targets, forwarded `ClrRestoreNonvolatileContext` to `RtlRestoreContext` for now

* Fix Alpine 3.13 ARM build
Alpine 3.13 is the first version of Alpine Linux that uses 64 bit time_t
on both 64 and 32 bit platforms. That breaks the build as we assumed
that 32 bit platforms use always 32 bit time_t.
This change fixes it by making the PAL time_t type always 64 bit.
Everything still works fine on non-Alpine ARM / x86 Linuxes, since
it only changes the time_t type size outside of PAL.

On Linux, libnuma.so{.1} are symlinks to libnuma.so.1.0.0.
When installed from default package manager; Ubuntu (libnuma-dev) and
Alpine (numactl-dev), found these two symlinks:
`{libnuma.so,libnuma.so.1} -> libnuma.so.1.0.0`
On Fedora (numactl-libs):
`libnuma.so.1 -> libnuma.so.1.0.0`
(there is no version-less variant)
PR adjusts probing fallback flow based on this info.

* Setting Thread.Name sets the native thread name on MacOS.
Setting Thread.Name will now set the name of the native thread

may be included without the PAL (#46055)
This was done via simple substitution of the standard sized integer types, and dealing with the fallout. It is tested by using the ICorJitInfo interface directly within the crossgen2 jitinterface thunk library.
Effort was made to use a minimum number of casts, as casts in such a large change are likely to be wrong somewhere.
- Exceptions are the use of casting to handle some calls to the existing internal metadata api and around use of char16_t.
In addition, a small amount of logic from the PAL headers were pulled into the proper header to allow compilation in the presence of some SAL annotation, and other small details.

These free() calls are done in the middle of the method body; it's
possible that a duplicate free() can be called on these at the cleanup
code that runs before the method returns. So set these pointers to null
after free()ing them to avoid free() already free()d memory.

If GetTempFileNameA fails, we don't free up the dynamically allocated

When SIGSEGV is not handled by .NET runtime (e.g. when it occurs in code
out of its control), the SIGSEGV handler ends up calling
DiagnosticServer::Shutdown in the runtime via a registered shutdown callback.
That method ends up calling Thread::GetFrame, which asserts if the
current SP is out of a valid range for the regular stack. The problem is
that SIGSEGV handler is called on an alternate stack and so this
callback ends up being called on that stack too. That causes this
assertion to fail, because the current thread is not marked as executing
on alternate stack, which would skip that assert.
This change fixes it by passing through a bool flag indicating whether
the callback was called on an alternate stack or not. And in that
callback, we set the flag on the thread accordingly.
