[llvm] Rename misleading `msvcrt` comment in `Windows/DynamicLibrary.inc` (PR #208884)

[via llvm-commits]

https://github.com/void2012 created https://github.com/llvm/llvm-project/pull/208884

The comment in function `DynamicLibrary::HandleSet::DLSym` referred to the mysterious `msvc.dll` windows standard dynamic library which simply doesn't exist and `msvcrt.dll` was likely meant, so fix the comments.
