  [lldb][NativePDB] Fix width and signedness of enum constants (#210338)

Enumerator values aren't always encoded in the correct bit width and
signedness. This happens with both MSVC and Clang.

On MSVC, unsigned 64bit enumerators can be encoded as signed. For
example `ULONGLONG_MAX` will be encoded as `-1`.
Clang/LLVM will always encode the values as unsigned.

Example: https://godbolt.org/z/96YjGW48W.

I fixed this by setting the expected width and signedness when creating
the enumerator constant. We can't use a shell test like for the other
PDB tests, because no output shows the enum values.
