Describe the issue

Asking google test to output to a non existing path, on a system with no notion of "./" being a path causes FilePath::CreateDirectoriesRecursively to end up in an infinite loop with stack overflow.

Steps to reproduce the problem

Somewhat hard.

• Run on an embedded system with file support, but no concept on a current directory named "./".
• Ask google-test to output xml to a non existing path.

What version of GoogleTest are you using?

6092810

Its also patch in a small way to work around: #1372

What operating system and version are you using?

rt-kernel

What compiler and version are you using?

arm-eabi-gcc (rt-collab toolbox 2022.1-0-gf81ad3e) 10.4.0

What build system are you using?

cmake version 3.25.0

Additional context

When creating directories recursively the stop condition is an empty pathname:

However, RemoveFileName() function will never end up with an empty pathname, but a ./ separator.
