Arm backend: Broaden exception handling for unsupported ops (#10473)

Previously, only AssertionError, RuntimeError, and ValueError were
caught during node translation failures in the TOSA backend. This patch
broadens the exception catch to all Exception types to ensure robust
error reporting via `dbg_fail()` even for unexpected errors.

This change helps avoid silent crashes or unhelpful tracebacks during
backend lowering of unsupported or misconfigured nodes.
