  -----------
  [flang][FIRToMemRef] lower `fir.coordinate_of` on static-extent arrays to indexed memref (#195404)

`fir.coordinate_of` on static array components (e.g. A%v(i)) was falling
back to a rank-0 scalar memref, losing index information and blocking
saffine parallelization. Lower these to a properly-shaped memref<dims x
T> with explicit indices. Dynamic arrays and struct-element arrays keep
the existing scalar fallback.
