target/arm: Fix VNCR fault detection logic

In arm_deliver_fault() we check for whether the fault is caused
by a data abort due to an access to a FEAT_NV2 sysreg in the
memory pointed to by the VNCR. Unfortunately part of the
condition checks the wrong argument to the function, meaning
that it would spuriously trigger, resulting in some instruction
aborts being taken to the wrong EL and reported incorrectly.

Use the right variable in the condition.

target/arm: Report VNCR_EL2 based faults correctly

If FEAT_NV2 redirects a system register access to a memory offset
from VNCR_EL2, that access might fault. In this case we need to
report the correct syndrome information:
* Data Abort, from same-EL
* no ISS information
* the VNCR bit (bit 13) is set

and the exception must be taken to EL2.

Save an appropriate syndrome template when generating code; we can
then use that to:
* select the right target EL
* reconstitute a correct final syndrome for the data abort
* report the right syndrome if we take a FEAT_RME granule protection
fault on the VNCR-based write

Note that because VNCR is bit 13, we must start keeping bit 13 in
template syndromes, by adjusting ARM_INSN_START_WORD2_SHIFT.

target/arm: Replace TARGET_PAGE_ENTRY_EXTRA

TARGET_PAGE_ENTRY_EXTRA is a macro that allows guests to specify additional
fields for caching with the full TLB entry. This macro is replaced with
a union in CPUTLBEntryFull, thus making CPUTLB target-agnostic at the
cost of slightly inflated CPUTLBEntryFull for non-arm guests.

Note, this is needed to ensure that fields in CPUTLB don't vary in
offset between various targets.

(arm is the only guest actually making use of this feature.)

target/arm: Explicitly select short-format FSR for M-profile

For M-profile, there is no guest-facing A-profile format FSR, but we
still use the env->exception.fsr field to pass fault information from
the point where a fault is raised to the code in
arm_v7m_cpu_do_interrupt() which interprets it and sets the M-profile
specific fault status registers. So it doesn't matter whether we
fill in env->exception.fsr in the short format or the LPAE format, as
long as both sides agree. As it happens arm_v7m_cpu_do_interrupt()
assumes short-form.

In compute_fsr_fsc() we weren't explicitly choosing short-form for
M-profile, but instead relied on it falling out in the wash because
arm_s1_regime_using_lpae_format() would be false. This was broken in
commit 452c67a4 when we added v8R support, because we said "PMSAv8 is
always LPAE format" (as it is for v8R), forgetting that we were
implicitly using this code path on M-profile. At that point we would
hit a g_assert_not_reached():
ERROR:../../target/arm/internals.h:549:arm_fi_to_lfsc: code should not be reached

#7 0x0000555555e055f7 in arm_fi_to_lfsc (fi=0x7fffecff9a90) at ../../target/arm/internals.h:549

at ../../target/arm/tlb_helper.c:260

The specific assertion changed when commit fcc7404eff24b4c added
"assert not M-profile" to arm_is_secure_below_el3(), because the
conditions being checked in compute_fsr_fsc() include
arm_el_is_aa64(), which will end up calling arm_is_secure_below_el3()
and asserting before we try to call arm_fi_to_lfsc():

#7 0x0000555555efaf43 in arm_is_secure_below_el3 (env=0x5555574665a0) at ../../target/arm/cpu.h:2396
#8 0x0000555555efb103 in arm_is_el2_enabled (env=0x5555574665a0) at ../../target/arm/cpu.h:2448
#9 0x0000555555efb204 in arm_el_is_aa64 (env=0x5555574665a0, el=1) at ../../target/arm/cpu.h:2509

Avoid the assertion and the incorrect FSR format selection by
explicitly making M-profile use the short-format in this function.

target/arm: Don't set ISV when reporting stage 1 faults in ESR_EL2

The syndrome value reported to ESR_EL2 should only contain the
detailed instruction syndrome information when the fault has been
caused by a stage 2 abort, not when the fault was a stage 1 abort
(i.e. caused by execution at EL2). We were getting this wrong and
reporting the detailed ISV information all the time.

Fix the bug by checking fi->stage2. Add a TODO comment noting the
cases where we'll have to come back and revisit this when we
implement FEAT_LS64 and friends.

Refactor to just pass a pointer to the fault info.
