  -----------
  [RISCV] Add macro fusion support for the Xqci extension instructions (#209542)

Add macro fusion definitions for the Qualcomm Xqci extension covering
movimm-alu, movimm-mul, movimm-ldst, movimm-jump, movimm-longlogical,
movimm-mov, mov-mov, mov-longlogical fusions.

The fusion definitions live in a new RISCVMacroFusionXQCI.td which is
included from RISCVMacroFusion.td. A MIR test and the feature list test
are updated accordingly.

To accomodate additional features, increased MAX_SUBTARGET_FEATURES to
448 (from 384).
