target/arm: Widen cnthctl_el2 to uint64_t
This is a 64-bit register on AArch64, even if the high 44 bits
are RES0. Because this is defined as ARM_CP_STATE_BOTH, we are
asserting that the cpreg field is 64-bits.

target/arm: Unify checking for M Main Extension in MRS/MSR
BASEPRI, FAULTMASK, and their _NS equivalents only exist on devices with
the Main Extension. However, the MRS instruction did not check this,
and the MSR instruction handled it inconsistently (warning BASEPRI, but
silently ignoring writes to BASEPRI_NS). Unify this behavior and always
warn when reading or writing any of these registers if the extension is
not present.

target/arm: Don't set EXC_RETURN.ES if Security Extension not present
In v7m_exception_taken(), for v8M we set the EXC_RETURN.ES bit if
either the exception targets Secure or if the CPU doesn't implement
the Security Extension. This is incorrect: the v8M Arm ARM specifies
that the ES bit should be RES0 if the Security Extension is not
implemented, and the pseudocode agrees.
Remove the incorrect condition, so that we leave the ES bit 0
if the Security Extension isn't implemented.
This doesn't have any guest-visible effects for our current set of
emulated CPUs, because all our v8M CPUs implement the Security
Extension; but it's worth fixing in case we add a v8M CPU without
the extension in future.

target/arm: implement DBGCLAIM registers
The architecture does not define any functionality for the CLAIM tag bits.
So we will just keep the raw bits, as per spec.

-----------
target/arm: provide stubs for more external debug registers
Qemu doesn't implement Debug Communication Channel, as well as the rest
of external debug interface. However, Microsoft Hyper-V in tries to
access some of those registers during an EL2 context switch.
Since there is no architectural way to not advertise support for external
debug, provide RAZ/WI stubs for OSDTRRX_EL1, OSDTRTX_EL1 and OSECCR_EL1
registers in the same way the rest of DCM is currently done. Do account
for access traps though with access_tda.

Move the ri == NULL case to the top of the function and return.

target/arm: Look up ARMCPRegInfo at runtime
Do not encode the pointer as a constant in the opcode stream.
This pointer is specific to the cpu that first generated the
translation, which runs into problems with both hot-pluggable
cpus and user-only threads, as cpus are removed. It's also a
potential correctness issue in the theoretical case of a
slightly-heterogenous system, because if CPU 0 generates a
TB and then CPU 1 executes it, CPU 1 will end up using CPU 0's
hash table, which might have a wrong set of registers in it.
(All our current systems are either completely homogenous,
M-profile, or have CPUs sufficiently different that they
wouldn't be sharing TBs anyway because the differences would
show up in the TB flags, so the correctness issue is only
theoretical, not practical.)
Perform the lookup in either helper_access_check_cp_reg,
or a new helper_lookup_cp_reg.
