Replace unmaintained BraviaRC backend with new fork: (#31234)

BraviaRC is currently unmaintained for home-assistant. This commit
    swaps it out with a new fork of BraviaRC called python-bravia-tv.
    This captures all bug fixes from BraviaRC release 3.7 (previously
    linked backend) to right before BraviaRC breaks when used by home-assistant.
    The intent of forking is to be able to continue supporting home-assistant.
    This is not intended to be a one off solution; this new fork will have
    future updates and be maintain as needed.

    This initial commit of python-bravia-tv improves the import process,
    however overall preserves the original API.
    Other fixes include:

    * Fix set-volume slider
    * Better error handling
    * Increase input options

    Resolves: #26351, #30964
    See also: #12577, #14843, #17345, #18245
