Dav1dPictures contain more than one buffer reference, so we're forced to use the
API properly to free them all.

Some of the assembly functions e.g. ff_h264_idct_dc_add_neon
has code like:
movrel x14, X(ff_h264_idct_add_neon)
Linker cannot resolve them fully at link time and emits dynamic
relocations.
Use explicit labels instead so that no dynamic relocations are
needed at all.
This avoids lld complains about text relocations.

The problem occurs in slice quant estimation and slice encoding:
If the slice quant is larger than MAX_STORED_Q we don't use pre-calculated
quant matrices, but generate a new one, but both qmat and qmat_chroma both
point to the same table, so the luma table ends up having chroma table
values.
Add custom_chroma_q the same way as custom_q.
