target/hla_target: set cortex_m->common_magic

Browse Source 
hla_target uses the same struct cortex_m_common as the standard cortex_m
target. Unlike the cortex_m target hla missed setting of common_magic.

Set commont_magic to help pointer verification.

Add convenience tests is_cortex_m_or_hla() and
is_cortex_m_with_dap_access()

Use proper test in cortex_m_verify_pointer() - this code relied on
unset common_magic on hla target before the change.
