Fix #36124: VSE - Input Color option does not work for video files

Byte images and movies will now fully follow input color space.
Before this non-sRGB input colorspace for byte images and movies
behave really doggy (results in preview and final render were
totally different).

To prevent data loss, if byte image is set not stored in sequencer's
space it'll be internally converted to float buffer.

In theory some setups might be rendering a bit different now, but
new behavior is totally expected and someone used non-sRGB input
space for byte images/movies had Convert Float enabled anyway.
