LoongArch: Use standard pattern name and RTX code for LSX/LASX rotate shift
Remove unnecessary UNSPECs and make the [x]vrotr[i] instructions useful
with GNU vectors and auto vectorization.

(lsx_vrotri_<lsxfmt>): Remove.
* config/loongarch/lasx.md (UNSPEC_LASX_XVROTR): Remove.
(lsx_vrotr_<lsxfmt>): Remove.
(lsx_vrotri_<lsxfmt>): Remove.
* config/loongarch/simd.md (bitimm): ... here. Expand it to
cover LASX modes.
(vrotr<mode>3): New define_insn.
(vrotri<mode>3): New define_insn.
