BaseTools: Clean up os.path.normcase and os.path.normpath usage

Refer to the docs of python, `os.path.normcase(path)` function:
"Normalize the case of a pathname. On Windows, convert all characters in
the pathname to lowercase, and also convert forward slashes to backward
slashes. On other operating systems, return the path unchanged."

`os.path.normpath(path)` also convert forward slashes to backward slashes.

So call `os.path.normcase` after `os.path.normpath` just convert path to
lowercase on Windows(only).

And Windows is case-insensitive but case-preserving.

So the usage of `os.path.normcase(os.path.normpath(path))` can be
simplified to `os.path.normpath(path)`. Then we can use case-preserving
paths rather than lowercase paths in compile_commands.json file
or build log.

But this patch continue to use `os.path.normcase`
when comparing/searching paths.
