Narayan Kalaburgi 9886db71d3 libhevcdec: Unify itrans_res family and remove redundant HBD implementation 
Currently, libhevc maintains two separate implementations for inverse
transform residual functions: ihevc_itrans_res_* and ihevc_hbd_itrans_res_*.

Since both 8-bit and HBD inverse transform residual routines output signed
16-bit residuals (WORD16 *pi2_dst), the only algorithmic difference between
8-bit and HBD variants is the 2nd stage shift:

    Stage 1 shift: IT_SHIFT_STAGE_1 = 7 (fixed across all bit depths)
    Stage 2 shift: shift = 20 - bit_depth
        - 8-bit:  20 - 8  = 12 (IT_SHIFT_STAGE_2)
        - 10-bit: 20 - 10 = 10

This commit cleans up the entire itrans_res family (4x4_ttype1, 4x4, dc, 8x8,
16x16, 32x32) as follows:

1. common/ihevc_itrans_res.h & common/ihevc_itrans_res.c:
   - Add 'UWORD8 bit_depth' parameter to ihevc_itrans_res_* function
     signatures and typedefs.
   - Replace hardcoded 'shift = IT_SHIFT_STAGE_2;' with 'shift = 20 - bit_depth;'.
   - Remove obsolete ihevc_hbd_itrans_res_* prototypes and typedefs.

2. common/ihevc_hbd_itrans_res.c:
   - Delete file (~2,335 redundant lines removed).

3. Update tests/common/ihevc_itrans_res_test.cc to test bit depths 8 and 10
