llvm-wrapper: fix warning C4244

llvm-wrapper/RustWrapper.cpp(1234): warning C4244: '=': conversion from 'uint64_t' to 'unsigned int', possible loss of data
nice consistency:

uint64_t https://github.com/llvm/llvm-project/blob/6009708b4367171ccdbf4b5905cb6a803753fe18/llvm/include/llvm/IR/DiagnosticInfo.h#L172
but unsigned https://github.com/llvm/llvm-project/blob/6009708b4367171ccdbf4b5905cb6a803753fe18/llvm/include/llvm/IR/DiagnosticInfo.h#L1091

llvm-wrapper: fix warning C4305

llvm-wrapper/ArchiveWrapper.cpp(70): warning C4305: 'argument': truncation from 'int' to 'bool'
while in llvm 12 signature was
 static ErrorOr<std::unique_ptr<MemoryBuffer>> getFile(const Twine &Filename, int64_t FileSize = -1, bool RequiresNullTerminator = true, bool IsVolatile = false);
https://github.com/llvm/llvm-project/blame/fed41342a82f5a3a9201819a82bf7a48313e296b/llvm/include/llvm/Support/MemoryBuffer.h#L85-L87

in llvm 13 and later it was changed to
static ErrorOr<std::unique_ptr<MemoryBuffer>> getFile(const Twine &Filename, bool IsText = false, bool RequiresNullTerminator = true, bool IsVolatile = false);
https://github.com/llvm/llvm-project/blame/75e33f71c2dae584b13a7d1186ae0a038ba98838/llvm/include/llvm/Support/MemoryBuffer.h#L86-L88

so code was interpreted as MemoryBuffer::getFile(Path, /*IsText*/true, /*RequiresNullTerminator=*/false), but now will be MemoryBuffer::getFile(Path, /*IsText*/false, /*RequiresNullTerminator=*/false). How that worked before?
