Zhao Zhili eedf8f0165 avcodec/hevc: workaround hevc-alpha videos generated by VideoToolbox ...

Apple VideoToolbox is the dominant producer of hevc-alpha videos, but
early versions generates non-standard VPS extensions that fail to
parse and return AVERROR_INVALIDDATA. Fix this by returning
AVERROR_PATCHWELCOME instead of AVERROR_INVALIDDATA for unsupported
VPS extension configurations. Setting poc_lsb_not_present for the
alpha layer in the fallback path when it has no direct dependency
on the base layer, so that IDR slices on the alpha layer won't
incorrectly read pic_order_cnt_lsb.

Fix #22384
