Python path case sensitivity issue on Windows (IDFGH-11666)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

What is the expected behavior?

idf.py does not complain about wrong python path when building project

What is the actual behavior?

When the path of python.exe recorded in project's build config is case-different on a case-insensitive filesystem (Windows), this error occurs:

'c:\work\esp32\.espressif\python_env\idf5.3_py3.11_env\Scripts\python.exe' is currently active in the environment while the project was configured with 'C:\work\esp32\.espressif\python_env\idf5.3_py3.11_env\Scripts\python.exe'. Run 'idf.py fullclean' to start again.

the C: drive is identical to c: drive on Windows, but this is not taken into account

Steps to reproduce.

1. Build any ESP-IDF project in VSCode with vscode-esp-idf-extension on Windows
2. Try to build the same project from command line using idf.py build
   you should see the error as described above

@dyarkovoy, thanks for submitting also the PR which solves this.
I haven't been able to reproduce this issue but with the fix everything works as expected.

As you said, according to documentation and my tests the string path is changed only on Windows platform.
