tests/checkasm: hevc_pred: use pixel helpers for diagnostic output
Replace plain memcmp+fail() with checkasm_check_pixel_padded() for
DC, planar, and angular prediction tests. Use PIXEL_RECT for output
buffers instead of flat arrays.

This enables:
- Detailed per-pixel difference output when run with 'checkasm -v'
- Detection of out-of-bounds writes beyond the NxN block area
- Padding violation reporting (writes past block boundary)

Previously, a test failure would only report "FAILED" with no
information about which pixels were wrong, making assembly debugging
difficult. Follows the pattern established in 4d4b301e4a (checkasm:
hevc_pel: Use helpers for checking for writes out of bounds).
