Subject: [PATCH] Add cortex_passes Buck target and fix quantizer dep

Summary: Add a new `cortex_passes` Python library target in `backends/cortex_m/passes` containing the CortexMPassManager and its constituent passes (activation fusion, convert-to-cortex-m, decompose hardswish/mean, quantized clamp activation, clamp hardswish). These were previously not in any Buck target, making CortexMQuantizer unusable from Buck builds.
