Vivek R Jadhav 36cb41a03d libhevcdec: Fix slice QP delta lower bound validation for HBD 
According to ITU-T H.265 Section 7.4.7.1, the initial SliceQpY value
shall be in the range of -QpBdOffsetY to +51, inclusive, where
QpBdOffsetY = 6 * (bit_depth_luma - 8).

Previously, the slice_qp_delta validity check in ihevcd_parse_slice_header
assumed an 8-bit lower bound of MIN_HEVC_QP (0), causing valid negative
slice QP values in high bit depth (10-bit/12-bit) streams to fail header
parsing with IHEVCD_INVALID_PARAMETER.

Updated the lower bound check to account for (6 * bit_depth_luma_minus8),
allowing valid HBD low QP bitstreams (such as QP = 0) to parse and decode
correctly.

Test: ./hevcdec
