fresnel-fourier iter3 Phase 6 commit A: VP8 enumeration + dispatch in config.c

Browse Source 
Three sites enabling VP8 profile recognition through the libva config
path:

  1. RequestQueryConfigProfiles: NEW enumeration block probing
     V4L2_PIX_FMT_VP8_FRAME against single + MPLANE OUTPUT formats.
     Mirrors iter2 HEVC enumeration block. Surfaces VAProfileVP8
     Version0_3 in vainfo on hantro env binding.

  2. RequestCreateConfig: NEW case VAProfileVP8Version0_3 with
     break — same shape as iter1 MPEG-2 + iter2 HEVCMain (no
     profile-specific config validation in the libva backend;
     validation deferred to vaCreateContext / control submission).

  3. RequestQueryConfigEntrypoints: VAProfileVP8Version0_3 added to
     the existing fall-through case list — surfaces VAEntrypointVLD.

After this commit alone, vainfo lists VP8Version0_3 (Phase 1
criterion 1) but vaCreateContext / runtime decode would fail at
later stages because no codec dispatcher exists yet (added in
commit B + C).
