   [flang][FIRToMemRef] Do not peel storage-association views (#222376)

After #215402, peelZeroOffsetViews walked through fir.convert that
changes the pointee type (e.g. !fir.ref<complex<T>> → !fir.ref<T>).
Load/store then indexed the parent array and converted the value, which
is wrong for Fortran storage association: it fails verification
(memref.store / illegal fir.convert) or silently changes bits (sitofp /
fpext).

Stop peeling when the accessed element type changes. Marshal the typed
view as a rank-0 memref of the dummy type. Same-type wrappers
(fir.declare, ref<T> → ref<T>) still peel to fir.array_coor.
