added support for search and setup WSL for `[amd64_]arm64` #8847

cocoa-xu · 2024-09-23T10:18:42Z

This PR is one of the smaller PRs separated from the original PR #8142 that attempts to add initial support for ARM64 windows.

In this PR,

SetupWSLcross.bat can also accept either arm64 or amd64_arm64 (x64_arm64) for its first parameter

arm64, amd64_arm64 and x64_arm64 are the official values used in the vcvarsall.bat script, vcvarsall syntax.

arm64 means to set up the environment when compiling natively, whereas amd64_arm64 and x64_arm64 means to set up the cross-compiling environment on an amd64 host machine for the arm64 target machine.
Updated relevant lines for setting the path for cl.exe

When cross-compiling, e.g., after executing vcvarsall.bat amd64_arm64, we can see two cl.exe in PATH with the first one being the cross-compiler for the arm64 target, and the second one being the native compiler for the amd64 host machine.
```
> where cl.exe
INFO: Could not find files for the given pattern(s).
> C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat amd64_arm64
> where cl.exe
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\bin\Hostx64\arm64\cl.exe
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\bin\Hostx64\x64\cl.exe
```
In this script, CL_PATH should be set to the directory that contains the cross-compiler, therefore, we need to remember the first one in _cl_exec_ and then break from the for-loop.
