softmmu: Use async_run_on_cpu in tcg_commit
After system startup, run the update to memory_dispatch
and the tlb_flush on the cpu. This eliminates a race,
wherein a running cpu sees the memory_dispatch change
but has not yet seen the tlb_flush.
Since the update now happens on the cpu, we need not use
qatomic_rcu_read to protect the read of memory_dispatch.

target/i386: add support for VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE
Current QEMU can expose waitpkg to guests when it is available. However,
VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE is still not recognized and
masked by QEMU. This can lead to an unexpected situation when a L1
hypervisor wants to expose waitpkg to a L2 guest. The L1 hypervisor can
assume that VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE exists as waitpkg is
available. The L1 hypervisor then can accidentally expose waitpkg to the
L2 guest. This will cause invalid opcode exception in the L2 guest when
it executes waitpkg related instructions.
This patch adds VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE support, and
sets up dependency between the bit and CPUID_7_0_ECX_WAITPKG. QEMU should
not expose waitpkg feature if VMX_SECONDARY_EXEC_ENABLE_USER_WAIT_PAUSE is
not available to avoid unexpected invalid opcode exception in L2 guests.

ensuregroup allows to specify both the acceptable versions of avocado,
and a locked version to be used when avocado is not installed as a system
pacakge. This lets us install avocado in pyvenv/ using "mkvenv.py" and
reuse the distro package on Fedora and CentOS Stream (the only distros
where it's available).
ensuregroup's usage of "(>=..., <=...)" constraints when evaluating
the distro package, and "==" constraints when installing it from PyPI,
makes it possible to avoid conflicts between the known-good version and
a package plugins included in the distro.
This is because package plugins have "==" constraints on the version
that is included in the distro, and, using "pip install avocado==88.1"
on a venv that includes system packages will result in an error:
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
But at the same time, if the venv does not include a system distribution
of avocado then we can install a known-good version and stick to LTS
releases.

configure: switch to ensuregroup
Using the new ensuregroup command, the desired versions of meson and
sphinx can be placed in pythondeps.toml rather than configure.
The meson.install entry in pythondeps.toml matches the version that is
found in python/wheels. This ensures that mkvenv.py uses the bundled
wheel even if PyPI is enabled; thus not introducing warnings or errors
from versions that are more recent than the one used in CI.
The sphinx entries match what is shipped in Fedora 38. It's the
last release that has support for older versions of Python (sphinx 6.0
requires Python 3.8) and especially docutils (of which sphinx 6.0 requires
version 0.18). This is important because Ubuntu 20.04 has docutils 0.14
and Debian 11 has docutils 0.16.

python: mkvenv: add ensuregroup command
Introduce a new subcommand that retrieves the packages to be installed
from a TOML file. This allows being more flexible in using the system
version of a package, while at the same time using a known-good version
when installing the package. This is important for packages that
sometimes have backwards-incompatible changes or that depend on
specific versions of their dependencies.
Compared to JSON, TOML is more human readable and easier to edit. A
parser is available in 3.11 but also available as a small (12k) package
for older versions, tomli. While tomli is bundled with pip, this is only
true of recent versions of pip. Of all the supported OSes pretty much
only FreeBSD has a recent enough version of pip while staying on Python
<3.11. So we cannot use the same trick that is in place for distlib.
