target/armv7m: rework Cortex-M register handling part 3

Move primask/basepri/faultmask/control packing/unpacking from
cortex_m.c and hla_target.c to armv7m.c armv7m_read_core_reg()
and armv7m_write_core_reg() where also the FP 32/64-bit registers
conversion takes place.

Introduce a new hidden register ARMV7M_PMSK_BPRI_FLTMSK_CTRL
for packing/unpacking of special registers in the register cache.

The new packing/unpacking is endianess safe.

While on it improve returned error codes and LOG_ messages.

Just minimal changes in cortex_m.c and hla_target.c, will be
consolidated in the next patch.
