Move it to hevc_ps as well. This is in preparation for a following patch.

hevcdec: move decoder-independent declarations into a separate header
Merged-by: James Almer <jamrial@gmail.com>
This way they can be reused by other code without including the whole
decoder-specific hevcdec.h
Also, add the HEVC_ prefix to them, since similarly named values exist
for H.264 as well and are sometimes used in the same code.
This fixes retrieving a valid profile for many of the FATE conformance samples,
allowing them to be properly decoded by the HWAccel after adding a profile check.

When only one sublayer is present, no information is coded. Only when at least two
are present, all 8 sublayers are written.

ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.
