Adds support for texture-based AMD encoding, with both H264, HEVC, and
HDR support. Falls back to FFmpeg when texture-based encoding cannot be
used for whatever reason.
(Jim note: This is based upon obsproject/obs-studio#4538 by AMD/Luxoft
with fewer files, FFmpeg fallback for software encoding, and HDR
support. I also went to lengths to ensure that FFmpeg command line
parameters also works with it)

This changes the way obs-scripting looks for and loads an available
Python 3 library. It tries to find a best possible version (starting
with Python 3.10) down to and including Python 3.6 by existing file
naming conventions and loads the most recent variant it can find.
User specified search path is either a Python installation directory
(Windows), or a Framework directory containing `Python.framework`
(macOS). The dll or dylib names are composed automatically.
The Python home path is also composed automatically on macOS (where
it has to point inside the Framework directory).
This feature is meant to reduce maximum audio buffering and turn off
dynamic buffering mode. This allows the lowest possible consistent
latency for audio buffering, which is useful for the decklink and NDI
outputs which cannot rely on audio timestamps for synchronization.
This can have a negative effect of making audio segments (partial or in
full) cut out. So audio glitching or audio loss can occur if this is
enabled.
Existing code didn't check for possible "empty" linked libraries
(e.g. Threads::Threads when compiler has built-in pthreads support).
Also adds support for compile options defined on linked dependencies.
Certain services have custom server lits handling which I had forgotten
about, so although it would have been nice to have this refactor, we'll
have to live with relying on the plugin properties object directly for a
while.
This also reverts obsproject/obs-studio#6530 and
obsproject/obs-studio#6683 because that change depended on this
problematic refactor code.
This reverts commits:
