Espressif mirror now uses Espressif cn PyPI registry for python packages

[brianignacio5]

Description

This pull request introduces support for selecting an ESP-IDF Python package mirror during setup, enabling users to specify which mirror to use for Python requirements installation. The changes propagate the new mirror parameter through the setup flow, ensuring it is passed to all relevant functions and used to set the appropriate environment variable for pip. Additionally, there are minor code cleanups and bug fixes in the setup logic.

Support for ESP-IDF Python package mirror selection:

• Added a mirror parameter to the setup flow, including functions such as installPythonEnvFromIdfTools, installPyReqs, createPyReqs, and downloadIdfTools, allowing users to specify which Python package mirror to use. [1] [2] [3] [4]
• Set the PIP_INDEX_URL environment variable to the Espressif mirror (https://dl.espressif.cn/pypi) when the selected mirror is ESP.IdfMirror.Espressif, ensuring pip uses the correct source for package installation.

Integration of mirror selection in setup UI and store:

• Updated the setup store and UI logic to include the selected mirror (selectedIdfMirror.value) when checking ESP-IDF tools and posting setup messages, ensuring the mirror choice is respected throughout the process.

Propagation of mirror parameter through setup classes and functions:

• Passed the mirror parameter through the SetupPanel class methods and related function calls, maintaining consistency and enabling correct environment configuration. [1] [2] [3] [4]

Minor code cleanups and bug fixes:

• Fixed a bug in the setup store where .value was missing in the Python version selection logic, ensuring the correct path is used.
• Minor formatting and whitespace cleanups for improved readability and maintainability. [1] [2] [3]
