[compiler-rt] Silence warnings
This fixes a few of these warnings, when building with Clang ToT on
Windows:
```
[622/7618] Building CXX object
projects\compiler-rt\lib\sanitizer_common\CMakeFiles\RTSanitizerCommonSymbolizer.x86_64.dir\sanitizer_symbolizer_win.cpp.obj
C:\src\git\llvm-project\compiler-rt\lib\sanitizer_common\sanitizer_symbolizer_win.cpp(74,3):
warning: cast from 'FARPROC' (aka 'long long (*)()') to
'decltype(::StackWalk64) *' (aka 'int (*)(unsigned long, void *, void *,
_tagSTACKFRAME64 *, void *, int (*)(void *, unsigned long long, void *,
unsigned long, unsigned long *), void *(*)(void *, unsigned long long),
unsigned long long (*)(void *, unsigned long long), unsigned long long
(*)(void *, void *, _tagADDRESS64 *))') converts to incompatible
function type [-Wcast-function-type-mismatch]
```
This is similar to https://github.com/llvm/llvm-project/pull/97905
