Add basic support to run QEMU via kunit_tool. Add support for i386,
x86_64, arm, arm64, and a bunch more.

The first argument to namedtuple() should match the name of the type,
which wasn't the case for KconfigEntryBase.
Fixing this is enough to make mypy show no python typing errors again.

Don't use an O(nm) algorithm* and make it more readable by using a dict.
*Most obviously, it does a nested for-loop over the entire other config.
A bit more subtle, it calls .entries(), which constructs a set from the
list for _every_ outer iteration.

The authors of this tool were more familiar with a different
type-checker, https://github.com/google/pytype.
That's open source, but mypy seems more prevalent (and runs faster).
And unlike pytype, mypy doesn't try to infer types so it doesn't check
unanotated functions.
So annotate ~all functions in kunit tool to increase type-checking
coverage.
Note: per https://www.python.org/dev/peps/pep-0484/, `__init__()` should
be annotated as `-> None`.
Doing so makes mypy discover a number of new violations.
Exclude main() since we reuse `request` for the different types of
requests, which mypy isn't happy about.
This commit fixes all but one error, where `TestSuite.status` might be
None.

Commit 8b59cd81dc ("kbuild: ensure full rebuild when the compiler is
updated") introduced a new CONFIG option CONFIG_CC_VERSION_TEXT. On my
system, this is set to "gcc (GCC) 10.1.0" which breaks KUnit config
parsing which did not like the spaces in the string.
Fix this by updating the regex to allow strings containing spaces.

Rework kunit_tool in order to allow .kunitconfig files to better enforce
that disabled items in .kunitconfig are disabled in the generated
.config.
Previously, kunit_tool simply enforced that any line present in
.kunitconfig was also present in .config, but this could cause problems
if a config option was disabled in .kunitconfig, but not listed in .config
due to (for example) having disabled dependencies.
To fix this, re-work the parser to track config names and values, and
require values to match unless they are explicitly disabled with the
"CONFIG_x is not set" comment (or by setting its value to 'n'). Those
"disabled" values will pass validation if omitted from the .config, but
not if they have a different value.

The ultimate goal is to create minimal isolated test binaries; in the
meantime we are using UML to provide the infrastructure to run tests, so
define an abstract way to configure and run tests that allow us to
change the context in which tests are built without affecting the user.
This also makes pretty and dynamic error reporting, and a lot of other
nice features easier.
kunit_config.py:
- parse .config and Kconfig files.
kunit_kernel.py: provides helper functions to:
- configure the kernel using kunitconfig.
- build the kernel with the appropriate configuration.
- provide function to invoke the kernel and stream the output back.
kunit_parser.py: parses raw logs returned out by kunit_kernel and
displays them in a user friendly way.
test_data/*: samples of test data for testing kunit.py, kunit_config.py,
etc.
