Add mechanism for adding overlay.dts files to the l4v build for all
architectures apart from X64 (which does not use dts files).
For example, place a file `overlays/ARM/overlay.dts` into the tree and
the build will pick it up as custom overlay file with the correct proof
session dependencies.
If no file is provided, an empty default overlay file is used.

This can be used by l4v proof runs in GitHub CI to save kernel build outputs
for later use by binary verification.

This includes replacing previous ASpec names for such constants with
the names used in Haskell/ExecSpec to avoid duplication. This also
makes some of the proofs slightly more generic.

Contrary to its name, this is not a lock file, contains versions used
to build things, and does not go away. I have been informed this is the
industry standard.
Removes files that were duplicated in cspec/$L4V_ARCH directories to exist directly in
the cspec directory and contain $L4V_ARCH switches where needed. This allows for a single
Makefile for building the C kernel and the KernelInc_C theory, which is different between
architectures, to still exist per L4V_ARCH.
As the build location of the C kernel, and the resulting kernel_all.c_pp artifact, is
moved this change needs to be reflected in all the theory files that refer to it.
The seL4 kernel now supports a CMake based build in addition to the original Make based
one. This changes the Makefile that previously included the kernel Makefile to instead
have rules for instantiating a sub CMake build
As the location of built files have changed the KernelInc_C theory also needs to be updated
to point to the new locations for the generated artifacts.

Per-plaform CPP configuration for spec-check and make-spec.
The configuration is still duplicated between the two scripts, but now
the translation/check for ARM_HYP will use correct CPP settings.
- replace ARM-specific constants and types with aliases which can be
instantiated separately for each architecture.
- expand lib with lemmas used in X64 proofs.
- simplify some proofs.

Architecture names follow L4V_ARCH-style naming conventions ('ARM', 'FAKE64').
However, the standalone parser does not make use of the L4V_ARCH environment
variable.
The standalone-parser Makefile builds all architectures at once, producing
binaries at 'ARM/c-parser', 'FAKE64/c-parser', and similarly for the tokenizer.
There are also wrapper scripts 'c-parser' and 'tokenizer' in the
standalone-parser directory, which take an architecture on the command line.
The make_munge.sh script calls the appropriate binary parser directly.
The idea of this file is to allow users to determine how the simpset,
cong set, intro set, wp sets, etc. have changed from an old version of
the repository to a new version.
The process is as follows:
1. A user runs "save_attributes" on an old, working version of the
theory.
2. This tool will write out a ".foo.attrib_trace" file for each
theory processed.
3. The user modifies imports statements as required, possibly
breaking the proof.
4. The user can now run "diff_attributes" to determine what
commands they should run to restore the simpset / congset /etc
to something closer to the old version.
The tool is not complete, in that it won't always suggest the full set
of "simp add", "simp del", etc commands. Nor does it know that a rule
added to the simpset is causing a problem. It merely lists
a hopefully-sensible set of differences.
