target-arm: Fix CPU breakpoint handling

A QEMU breakpoint match is not definitely an architectural breakpoint
match. If an exception is generated unconditionally during translation,
it is hardly possible to ignore it in the debug exception handler.

Generate a call to a helper to check CPU breakpoints and raise an
exception only if any breakpoint matches architecturally.
