Bazel client; implement NormalizePath
This method can normalize paths with "." and ".."
and multiple "/" characters.
E.g. normalize("../foo/./bar/../baz") = "foo/baz"
This method enables us implementing PathExists on
Windows. If the path to check is too long, we need
to prefix it with "\\?\" for the Windows API
functions to work, but then the path must be
fully normalized and in Windows format. We already
have functions to convert a path to Windows format
but that doesn't normalize; with this function we
can finally convert paths like "/c/foo/../bar" to
L"\\?\c:\foo" and check if it exists.

{Fast, Correct} - Choose two
Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:
A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.
An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.
Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
