[PATCH v8 0/6] MR188: vkd3d-shader/tpf: Add support for emitting sample_l instructions

[Ethan Lee (＠flibitijibibo)]

From what I can tell, the recent work on SampleBias/SampleLevel did all of the work for us, we just need to take the same framework and include the case for the `sample_l` instruction.

Tested with some shaders from the native Linux version of Little Racers STREET.
