x86/crc-t10dif: implement crc_t10dif using new template

Instantiate crc-pclmul-template.S for crc_t10dif and delete the original
PCLMULQDQ optimized implementation.  This has the following advantages:

- Less CRC-variant-specific code.
- VPCLMULQDQ support, greatly improving performance on sufficiently long
  messages on newer CPUs.
- A faster reduction from 128 bits to the final CRC.
- Support for i386.

Benchmark results on AMD Ryzen 9 9950X (Zen 5) using crc_kunit:
