libs: encoder: h265: chroma and luma with format

Browse source 
If the profile is main-10 the bit_depth_luma_minus8, in the sequence
parameter buffer, shall be the color format bit depth minus 8, 10-8
which is 2. Also for bit_depth_chroma_minus8.

This patch gets the negotiated sink caps format and queries its
luma's depth and uses that value to fill the mentioned parameters.
