Some of the defines are outdated and never actually set, and the
remaining ones can be easily set through existing or easily added
ifdefs.

Originally, we only were using bindgen for stylo, and we also went a bit
overkill by including a lot of extra CFLAGS in there, which end up
being unnecessary. So we now only pass a more minimal set of flags, and
add some extra CFLAGS in cases where they are necessary.

While the use of toml allows the flags to be separated, the split is
done via some shell shenanigans anyways, and servo's build.rs can
handle the same just fine.

Allow for downstream projects such as Thunderbird to set different GUIDs for
AccessibleHandler to avoid clashes when both applications are installed.
The GUIDs themselves can be defined in confvars.sh or in branding/configure.sh
depending on the specific needs of the application. Fallback GUIDs are in
old-configure.

At the same time, move the option to python configure, which changes how
to disable it (setting to an empty value rather than 0).

The MOZ_UA_OS_AGNOSTIC #ifdefs were added for Firefox OS because it hoped to omit OS ("Firefox OS" or "Android") in its UA string.

The build always uses them anyways, but configure tests don't, and some
of them fail as a consequence in some cases (example: when UBsan is
enabled, all AC_LANG_CPLUSPLUS + AC_CHECK_FUNCS tests fail). We also had
similar problems in the past, such as bug 1513605.
By adding the PIC flags to CFLAGS and CXXFLAGS, we ensure old-configure
tests use the flags as well.
While here, we also remove DSO_CFLAGS, which was always empty, and we
stop passing -fPIC to wasm compiles, because it has no effect there.

There is only one place where it's used:
config/check_vanilla_allocations.py, which is only executed from
js/src/build/Makefile.in on the condition that the build is targeting
Linux and not LTO. But the LTO test is actually outdated, because we
don't build with `-flto`, but `-flto=thin`, so the exclusion doesn't
work anymore.
There is however no AC_CHECK_PROG, and we currently rely on NM to be
given, or fall back to "nm", which works in most cases, except LTO with
clang. It works on CI because in LTO builds we explicitly set NM to
llvm-nm (which can output symbols from LLVM bitcode objects), but we
could also do that automatically.
So we add a full detection of nm/llvm-nm to python configure, and limit
it to Linux, since we only ever use it there.

In cross-compiled Windows builds, our binaries embed PDB paths like /builds/worker/... which breaks some Windows tools that expect Windows-style paths. This patch sets `-PDBALTPATH:%_PDB%` which instructs the linker to emit only the basename. That's apparently enough that the tools can still find the right symbols.

In clang trunk 12, mingw builds started adding an `.exe` extension by default. We need to have `ac_exeext` know about this so that we'll search for `conftest.exe` rather than `conftest`. Calling `AC_EXEEXT` will go through some logic and set the right value of `ac_exeext`.
