QEMU for x86 has a nasty CPU hotplug bug of which the ramifications are
difficult to oversee, even though KVM acceleration seems to be
unaffected. This has been addressed in QEMU mainline, and will percolate
through the ecosystem at its usual pace. In the mean time, due to the
potential impact on production workloads, we will be updating OVMF to
abort the boot when it detects a QEMU build that is affected.
Tiancore's platform CI uses QEMU in TCG mode, and is therefore impacted
by this mitigation, unless its QEMU builds are updated. This has been
done for Ubuntu-GCC5, but Windows-VS2019 still uses a QEMU build that is
affected.
Aborting the boot upon detecting the QEMU issue will render all boot
tests carried out on Windows-VS2019 broken unless we implement the
'escape hatch' that enables proceed-at-your-own-risk mode, and permits
the boot to proceed even if the QEMU issue is detected.
So let's enable this for Windows-VS2019, and remove it again once it is
no longer needed.

Run the Linux jobs of the OvmfPkg platform CI inside a container,
in the same way the general CI does now. Make use of the default image
specified in the defaults.yml template.
Do not run apt-get in CI jobs to install qemu and gcc dependencies.
Assume the container image provides these.
Use Python from the container image, do not download at runtime.

Use the default Python version from the defaults template
(.azurepipelines/templates/defaults.yml) in the Windows and
Linux CI jobs.
Previous changes to the CI job templates make it necessary
to specify a version number, if Python shall be pulled
at CI runtime.

Rename TPM_ENABLE to TPM2_ENABLE so naming is in line with the
ArmVirtPkg config option name.
Add separate TPM1_ENABLE option for TPM 1.2 support.

Drop TPM_CONFIG_ENABLE config option. Including TPM support in the
build without also including the TPM configuration menu is not useful.

Building grub.efi for AmdSev is difficult because it depends on patches
not yet merged to upstream grub. So shortcut the grub build by simply
creating an empty grub.efi file. That allows to at least build-test the
AmdSev variant.

Move SettingsManager and PlatformBuilder classes to PlatformBuildLib.py
file, keep only CommonPlatform class in PlatformBuild.py. Allows
reusing these classes for other builds. Pure code motion, no functional
change.
