x86/hevc_idct: replace old and unused idct functions
Only 8-bit and 10-bit idct_dc() functions are included (adding others should be trivial).
Benchmarks on an Intel Core i5-4200U:
idct8x8_dc
SSE2 MMXEXT C
cycles 22 26 57
idct16x16_dc
AVX2 SSE2 C
cycles 27 32 249
idct32x32_dc
AVX2 SSE2 C
cycles 62 126 1375
