* Remove libuuid usage
This change removes dependency on the libuuid library that is used for GUID creation only.
It implements it using a random generator instead.
It also modifies return type of PAL_Random to VOID since it was always
returning TRUE and none of the existing callers were checking it.
1. Port the GUID creation to managed code.
2. Modify the PAL_Random to have 6 times better perf so that the perf of the
CoCreateGuid that is used in the native runtime doesn't degrade that much
w.r.t the previous state when the libuuid was used.
3. Use Interop.GetRandomBytes on Unix and fix Windows
