roms/Makefile.edk2: prepare for replacing TPM2*_ENABLE macros
Ekd2 commit 07952a962a40 ("OvmfPkg: rename TPM2 config prefix to TPM",
2020-03-04), part of edk2-stable202005, renamed OVMF's TPM2*_ENABLE build
flags to TPM*_ENABLE. Going forward, the TPM*_ENABLE flags would activate
both TPM1.2 and TPM2.0 support.
In order to build OVMF at edk2-stable202008 without losing currently
enabled functionality, insert the new flags as no-ops now. We'll remove
the old flags after advancing with the edk2 submodule.

roms/efirom, tests/uefi-test-tools: update edk2's own submodules first
In edk2 commit 06033f5abad3 ("BaseTools: Make brotli a submodule",
2020-04-16), part of edk2-stable202005, the Brotli compressor /
decompressor source code that edk2 had flattened into BaseTools was
replaced with a git submodule.
This means we have to initialize edk2's own submodules before building
BaseTools not just in "roms/Makefile.edk2", but in "roms/Makefile" (for
the sake of the "efirom" target) and "tests/uefi-test-tools/Makefile" as
well.
Right now this patch is effectively a no-op; it will become meaningful
after we move the edk2 submodule to edk2-stable202008.

The reason of the error is explained by Adam Leventhal [1]:
Note that is-enabled probes don't have the stability magic so I'm not
sure how things would work if only is-enabled probes were used.
net/colo code uses is-enabled probes to determine if other probes should
be used but colo_compare_miscompare itself is not used explicitly.
Linker doesn't include the symbol and build fails.
The issue can be resolved if is-enabled probe matches the actual trace
point that is used inside the test. Packet dump toggle is replaced with
a compile-time conditional definition.

qom: provide convenient macros for declaring and defining types
When creating new QOM types, there is a lot of boilerplate code that
must be repeated using a standard pattern. This is tedious to write
and liable to suffer from subtle inconsistencies. Thus it would
benefit from some simple automation.
QOM was loosely inspired by GLib's GObject, and indeed GObject suffers
from the same burden of boilerplate code, but has long provided a set of
macros to eliminate this burden in the source implementation. More
recently it has also provided a set of macros to eliminate this burden
in the header declaration.
In GLib there are the G_DECLARE_* and G_DEFINE_* family of macros
for the header declaration and source implementation respectively:
Note that these macros are including support for g_autoptr() for the
object types, which is something previously only supported for variables
declared as the base Object * type.
IOW, in both cases the maintainer now only has to think about the
interesting part of the code which implements useful functionality
and avoids much of the boilerplate.
