[clang] [CIR][AArch64] Lower NEON vuzp1/2 intrinsics (PR #195527)

 The vuzp1 and vuzp2 intrinsic tests were moved out to the new neon/perm.c file. A small fix was needed: the  
  first remaining test (test_vtrn1_s8) now needs to capture the ATTR0 FileCheck variable since the previous
  definition (on the first vuzp1 test) was removed. Changed #[[ATTR0]] to #[[ATTR0:[0-9]+]] to capture the     
  attribute group number inline.
