This PR is to allow a compiler warning even when all warnings
are requested to be treated as errors.
The following pattern is very common in Slang code base:
if (auto var = as<...>(...))
And when `var` is not used, the compiler prints a warning.
Alternatively we can remove `auto var =` part but there are too many.

This PR fixes the compiler warning like following,
lld-link: warning: ignoring unknown argument '--no-undefined'
lld-link: warning: ignoring unknown argument '--build-id', did you mean '-build-id'
chatGPT said that those options are for ELF and not for Windows:
These warnings happen because the Clang toolchain on Windows is invoking lld-link, which is the LLVM linker frontend for link.exe compatibility (i.e., it acts like the MSVC linker). The arguments --no-undefined and --build-id are ELF-specific flags, which are valid when targeting Linux, but not valid in the PE/COFF (Windows) environment.
Here's a breakdown:
⚠️ Warning messages explained:
lld-link: warning: ignoring unknown argument '--no-undefined'
→ This is a Linux/ELF flag. On Windows, this has no effect and is unknown.
lld-link: warning: ignoring unknown argument '--build-id', did you mean '-build-id'
→ Again, --build-id is for ELF binaries to include a unique build ID. Not valid for Windows targets.

The previous attempt to enable Structured Exception Handling in
(only) MSVC using the /EHa compiler flag caused trouble with flags
defined with Cmake Generator Expressions. These expressions are
not fully resolved, and they fail validation checks in
check_cxx_compiler_flag(). The previous attempt at applying
/EHa to only MVSC involved refactoring a direct call to
target_compile_options() with a call to the Slang helper function
add_supported_cxx_flags() where an additional MSVC filter was
introduced, but the helper also calls check_cxx_compiler_flag() to
see if flags are supported. It was okay for /EHa, but not some
other flags that ended up getting newly validated.
The above issue is fixed by re-implementing the change that added
/EHa to only MSVC. This change goes back to adding compiler flags
without the helper function with its extra validation, instead using
an additional cmake generator expression to apply /EHa only to MSVC.

Catch all exceptions in render-test
In MSVC, the /EHsc flag is used by default,
it causes only C++ (synchronous) exceptions
to be caught by try/catch blocks.
The /EHa flag can instead be used to catch
both synchronous C++ exceptions as well
as structured asynchronous exceptions
such as those seen in segfaults or other
typical bugs.
Using /EHa allows render-test to not crash
completely if there is a buggy graphics driver in the system.
