Remove vestigial HEVC_DEC_PROFILE_T enum and e_profile member from codec_t, along with its hardcoded initialization in ihevcd_init and assignment block in ihevcd_parse_sps. All dynamic bit depth, pixel size, and function selection logic in HBD relies directly on bitstream syntax elements.

Fix heap-buffer-overflow in HBD padding due to bit depth change.
...
Trigger IVD_RES_CHANGED when bit depth or chroma format changes in SPS,
forcing reallocation of picture buffers.
To prevent corrupting the codec state on invalid SPS parses, the updates to
global codec parameters (like i4_pixel_size_y and i4_bit_depth_luma) are
deferred to the end of ihevcd_parse_sps, after all validation checks have
passed. The resolution change check now compares the old active values in
ps_codec against the newly parsed values in the temporary ps_sps structure.

libhevcdec: Add support for extended profile parsing from SPS headers
...
- Update ihevcd_parse_sps to parse profile dynamically from clip SPS (profile_idc, chroma format, bit depth, intra and still constraint flags).
- Add support for Main, Main 10, Main 10 Still, Main 422 10, Main 444, Main 444 10, Main Intra, Main 10 Intra, Main 422 10 Intra, Main 444 Intra, Main 444 10 Intra, and Main 444 Still Picture profiles.
- Allow profile_idc == 4 (RExt) in SPS profile validation checks.
- Update pixel size determination in ihevcd_api.c for 8-bit vs 10-bit profiles.
- Add CLI argument parsing for new profiles in main.c.

libhevcdec: Enable architecture-specific SIMD optimizations for 422 and 444
...
Previously, when 422 or 444 chroma formats were encountered, all
function pointers were overridden to generic C implementations due to
lack of support in optimized assemblies/intrinsics for certain
components.
This change introduces `ihevcd_init_function_ptr_rext` which:
- First initializes all function pointers with architecture-optimized
versions.
- Explicitly overrides only the components not yet optimized for 422/444 formats (intra prediction, SAO, deblocking and chroma padding) to point
back to their C implementations.
This allows other fully-compatible modules (e.g: inter prediction modes, transform/reconstruction, format conversion) to benefit from SIMD
optimizations on 422/444 formats without degrading YUV 420 decoding.
Test: ./hevcdec

format allowed. That is, for a given chroma format idc not all output
color formats are supported. The output format can now be either same
as internal color format or 420p.

Add few more checks for invalid parameters in sps
...
Following elements didn't have a bound check in SPS as spec doesn't list
the bounds on these explicitly.
log2_min_coding_block_size_minus3, log2_diff_max_min_coding_block_size,
log2_min_transform_block_size_minus2 and log2_diff_max_min_transform_block_size
Added appopriate error checks on these fields
