MLBEDSW-3377: fixup_stridedslice_output may silently change CPU ops
This commit removes the constraint on all tensor
shapes matching the OFM shape.
The motivation is that this constraint essentially
only checks that the fixup function has run.
This means that it removes the possibility for the
fixup function to run after the supported operator
check and this effectively means that any
StridedSlice operator that would be placed on the
CPU is still modified by the fixup function.
Because the fixup function is moved to after the
supported operators check, some unreachable cases
are removed from the fixup function.
