Modify FrameProcessor and MatrixTextureProcessor interfaces to support
different input and output color transfers. Does not implement conversion between
color ranges (ex. HDR and SDR), but should allow for conversion between color
transfers of the same color range (ex. HLG and PQ).
This supports in-app tone mapping, where we need a single FrameProcessor to
input HDR color transfers (ex. HLG/PQ) and output SDR (ex. gamma2.2). This also
supports previewing, where we need a single FrameProcessor to be able to input HLG
and output PQ.
Manually tested by confirming colors still look right on SDR and HDR videos
with a rotation and color affect applied.

From this CL on, FrameProcessor listeners will be invoked from an Executor that
is passed in when creating the FrameProcessor.
GlTextureProcessor needs to invoke the ErrorListener on the said Executor too.

Make it easier to support use of RGBA_101012 rather than RGBA_8888 for EGL
contexts, displays, and surfaces.
This tangentially supports adding HDR tests, by slightly simplifying the color
selection logic we'd have to add in HDR tests.
