Decompositions of GRU, LSTM and RNN were inserted in the Arm backend pass pipeline even though these operators would have been decomposed in the core-ATen legalization. Also moves tests from test/passes/ to test/modules/ as the tests are end-to-end tests rather than isolated pass tests.

pass pipline even though these operators would have been decomposed in
the core-ATen legalization. Also moves tests from test/passes/ to
test/modules/ as the tests are end-to-end tests rather than isolated

I guess the tests added by #17140 are green, so should be ok to merge.
