Fusion: automatic installation of PySide2 (#6111)

* OP-7450 - WIP of new hook to install PySide2

Currently not working yet as subprocess is invoking wrong `pip` which causes issue about missing `dataclasses`.

* OP-7450 - updates querying of PySide2 presence

Cannot use pip list as wrong pip from .venv is used and it was causing issue about missing dataclass (not in Python3.6).
This implementation is simpler and just tries to import PySide2.

* OP-7450 - typo

* OP-7450 - removed forgotten raise for debugging

* OP-7450 - double quotes

* OP-7450 - return if error

Co-authored-by: Jakub Trllo <43494761+iLLiCiTiT@users.noreply.github.com>

* OP-7450 - return False

* OP-7450 - added optionality for InstallPySideToFusion

New hook is controllable by Settings.

* OP-7450 - updated querying of Qt

This approach should be more generic, not tied to specific version of PySide2

* OP-7450 - fix unwanted change

* OP-7450 - added settings for legacy OP

* OP-7450 - use correct python executable name in Linux

Because it is not "expected" python in blender but installed python, I would expect the executable is python3 on linux/macos rather than python.

* OP-7450 - headless installation in Windows

It checks first that it would need admin privileges for installation, if not it installs headlessly. If yes, it will create separate dialog that will ask for admin privileges.

* OP-7450 - Hound

* Update openpype/hosts/fusion/hooks/pre_pyside_install.py
