  -----------
  [ARM] Remove unused lowerABS function. NFC

This function was added in D49837, but no setOperationAction call
was added with it. The code is equivalent to what is done by the
default ExpandIntRes_ABS implementation when ADDCARRY is supported.
Test case added to verify this. There was some existing coverage
from Thumb2 MVE tests, but they started from vectors.
