Fix Posix shell on Windows

[AntoinePrv]

• Fix Micromamba >v1.4.5 broken with cygwin #2683
• Alternative to Use generic_string for path on Windows unix shells #2685
• Based on Windows path manipulation and other cleanups #2801

[AntoinePrv]

@pavelzw I investigated the generic_string that does not give a / separator on Windows.
This is another shot, but I'm not sure if we should convert to say C:/folder/file.txt or /c/folder/file.txt (the former is easier).

[AntoinePrv]

@0xbe7a do you have time to give this a try?

[JohanMabille]

Waiting for feedback from users to see if that solves the problem.

Sadly it seems micromamba still does not work correctly with cygwin. I looks like it gets confused about /cygdrive/ and creates a new folder cygdrive under C:\

I don't know much about cygwin , cygdrive, default windows drive...

export MAMBA_ROOT_PREFIX='/cygdrive/c/Users/USERNAME/micromamba_prefix'

Is this one expected? What input did you provide? Would /c/Users/USERNAME/micromamba_prefix or C:/Users/USERNAME/micromamba_prefix work here?

I think if we can this input cleaned, the rest would not diverge.
