Provide a way to use python environment when using cmake-presets

### Brief Issue Summary
I would expect vscode-cmake-tools to invoke the cmake binary within the python virtual environment that is the currently chosen interpreter by the python extension when using cmake presets.

Currently, any python dependencies in a cmake workflow must be installed in the global python environment when using cmake-presets.

Start by reading the 18-comment discussion for decisions about how vscode-cmake-tools should interact with the Python extension and CMake presets. The work is done when a selected Python virtual environment is used for the preset workflow so its Python dependencies no longer need to be installed globally.
