Haven't tested it but this seems straight forward and simple. |

Unlike obs_nv12/p010_tex_active() this accurately reflects the texture availability in the mix associated with the encoder.
Use the recently added `obs_encoder_video_tex_active()` API for AMD AMF-based encoders, similar to the recent commit for obs-nvenc. This allows the OBS canvas to use non-NV12 pixel formats (such as I444) while the multitrack video encoders will use NV12 or P010 textures converted using the GPU.
Also sets Rec. 709/limited defaults for multitrack output.

Description
Extends GPU scaling to also handle colourspace or format conversions to enable shared-texture encoding with heterogenous output formats.
Motivation and Context
#11336 falls back to shared memory encoders, which are less efficient, this aims to fix that by extending the conversion capabilities.
In theory this would also allow recording HDR locally and streaming SDR, among other use cases that people might have.
Will need some additional discussion related to function naming and implemenation of the new texture availability check.
How Has This Been Tested?
Streamed to Twitch while recording 444 locally as well as streaming SDR while recording HDR locally.
This is part of the closed beta Twitch Enhanced Broadcasting build and seems to work fine so far.
