  -----------
  [AArch64][SME2/SVE2p1] Add predicate-as-counter intrinsics for pext (single)

These intrinsics are used to implement the pext intrinsics that extract
a predicate (mask) from a predicate-as-counter value, e.g.

   __attribute__((arm_streaming))
   svbool_t svpext_lane_c8(svcount_t pnn, uint64_t imm);

  Log Message:
  -----------
  [AArch64][SME2/SVE2p1] Add predicate-as-counter intrinsics for pext (multi)

These intrinsics are used to implement the pext intrinsics that extract
two predicates (mask) from a predicate-as-counter value, e.g.

  __attribute__((arm_streaming))
   svboolx2_t svpext_lane_c8_x2(svcount_t pnn, uint64_t imm);
