target/arm: Rename FPSR_MASK and FPCR_MASK and define them symbolically

Now that we store FPSR and FPCR separately, the FPSR_MASK and
FPCR_MASK macros are slightly confusingly named and the comment
describing them is out of date. Rename them to FPSCR_FPSR_MASK and
FPSCR_FPCR_MASK, document that they are the mask of which FPSCR bits
are architecturally mapped to which AArch64 register, and define them
symbolically rather than as hex values. (This latter requires
defining some extra macros for bits which we haven't previously
defined.)

target/arm: Support migration when FPSR/FPCR won't fit in the FPSCR

To support FPSR and FPCR bits that don't exist in the AArch32 FPSCR
view of floating point control and status (such as the FEAT_AFP ones),
we need to make sure those bits can be migrated. This commit allows
that, whilst maintaining backwards and forwards migration compatibility
for CPUs where there are no such bits:

On sending:
* If either the FPCR or the FPSR include set bits that are not
visible in the AArch32 FPSCR view of floating point control/status
then we send the FPCR and FPSR as two separate fields in a new
cpu/vfp/fpcr_fpsr subsection, and we send a 0 for the old
FPSCR field in cpu/vfp
* Otherwise, we don't send the fpcr_fpsr subsection, and we send
an FPSCR-format value in cpu/vfp as we did previously

On receiving:
* if we see a non-zero FPSCR field, that is the right information
* if we see a fpcr_fpsr subsection then that has the information
* if we see neither, then FPSCR/FPCR/FPSR are all zero on the source;
cpu_pre_load() ensures the CPU state defaults to that
* if we see both, then the migration source is buggy or malicious;
either the fpcr_fpsr or the FPSCR will "win" depending which
is first in the migration stream; we don't care which that is

We make the new FPCR and FPSR on-the-wire data be 64 bits, because
architecturally these registers are that wide, and this avoids the
need to engage in further migration-compatibility contortions in
future if some new architecture revision defines bits in the high
half of either register.

(We won't ever send the new migration subsection until we add support
for a CPU feature which enables setting overlapping FPCR bits, like
FEAT_AFP.)

target/arm: Implement FEAT WFxT and enable for '-cpu max'

FEAT_WFxT introduces new instructions WFIT and WFET, which are like
the existing WFI and WFE but allow the guest to pass a timeout value
in a register. The instructions will wait for an interrupt/event as
usual, but will also stop waiting when the value of CNTVCT_EL0 is
greater than or equal to the specified timeout value.

We implement WFIT by setting up a timer to expire at the right
point; when the timer expires it sets the EXITTB interrupt, which
will cause the CPU to leave the halted state. If we come out of
halt for some other reason, we unset the pending timer.

We implement WFET as a nop, which is architecturally permitted and
matches the way we currently make WFE a nop.
