* [wasm][bcl] TimeZoneInfo implementation for WebAssembly to read from WASM VFS `/zoneinfo`.
- Remove `TimeZoneInfo.WebAssembly.cs` file
- Remove source dependencies on `TimeZoneInfo.WebAssembly.cs`.
- Modify TimeZoneInfo for specific WASM functionality
- Default root directory is `zoneinfo`
- Add icall `mono_timezone_get_local_name` for WASM in CreateLocal
- Add icall implementation
- ves_icall_System_TimeZoneInfo_mono_timezone_get_local_name
* [wasm][build] Add `-s FORCE_FILESYSTEM=1` to mono wasm runtime build
- Required so that it includes support for loading pre preload packages
Message when generating the zoneinfo data.
> Remember to build the main file with -s FORCE_FILESYSTEM=1 so that it includes support for loading this file package
* [wasm] zoneinfo data and support files.
- Three files for zoneinfo VFS support.
- `mono-webassembly-zoneinfo-fs-smd.js.metadata` - This is the separate metadata output by emscripten file-packager. Used to parse the zoneinfo data in non browser environments. See `runtime-tests.js`
- `mono-webassembly-zoneinfo-fs.js` - Output by emscripten file-packager that will be referenced by browser environments to load the zoneinfo data into the VFS at `/zoneinfo`
- `zoneinfo.data` - The binary file output by emscripten file-packager. The file contains the actual zoneinfo data loaded into the VFS and parsed by `TimeZoneInfo`.
* [wasm][driver] Add backing support for icall `mono_timezone_get_local_name`
* Add TimeZone info test.
* [wasm][packger] Add `-s FORCE_FILESYSTEM=1`
- Required so that it includes support for loading preload packages
Message when generating the zoneinfo data.
> Remember to build the main file with -s FORCE_FILESYSTEM=1 so that it includes support for loading this file package
* Fix AOT tzd test
* Remove commented code lines for `TimeZoneInfo.WebAssembly.cs` module
* Regenerated zone info without --no-heap-copy as it causes problems. This will create a warning in browser for now.
* Add zoneinfo support files to package
* Fix TimeZoneInfo tests to use the `--enable-fs` packager parameter
* Add back icall implementation after rebase
- ves_icall_System_TimeZoneInfo_mono_timezone_get_local_name
* Add back backing support for icall `mono_timezone_get_local_name` after rebase
* Fix build error
* Add back zoneinfo tests to Makefile after rebase
* Fix packager zoneinfo sample builds.
