Description

Switch from fx.symbolic_trace to dynamo trace for converter test part-1

Since we ~2000 test cases I splited into batches to migrate them off fx.symbolic_trace

current batch: tests/py/dynamo/conversion/test_a*.py

There mainly two types of testcases require change:

for ops require custom dynamic shape support, will be changed to use dynamic_shapes instead of Input
for ops will be decomposed into multiple ops, these op test will be added in the test_composite_aten_op.py
