Adds the -fsanitize-blacklist option for CFI, using the built in
blacklist at external/compiler-rt/lib/cfi/cfi_blacklist.txt.
Also refactors the CFI cflags and ldflags into cc/makevars.go to
ensure they're consistent across Soong and make projects.
Bug: 30227045
Test: ENABLE_CFI=true m -j40 builds and boots.
Test: The blacklist prevents runtime errors that otherwise occur.

Ideally we'd calculate the headers that are written here too, but I'll
add that in a later change that actually enforces the generated header
list.

Export a list of libraries in the VNDK, which is currently empty.
Take in Make's global BOARD_VNDK_VERSION, and use that as the SDK
version for modules that specify use_vndk: true.
Modules that use the vndk have some configuration as if they were
building against the NDK (the absence of globally defined headers), but
in other cases look like platform modules (using the platform libc++,
for now).
This change does not attempt to enforce any linking constraints, that
will come in a later patch.
Test: out/soong/build.ninja doesn't change

For every file which we can run clang-tidy (C/C++ clang-built), we add a
new build node that depends on the object file (since clang-tidy does
not export a depfile), and is depended on by the link step. This is
better than how we're doing it in make, since calling tidy can be turned
on or off without needing to rebuild the object files.
This does not attempt to port WITH_TIDY_ONLY from Make, since the way
that it works is broken (due to the lack of a depfile).

This matters for C files that are also built for Windows. Previously they'd
be compiled with -std=gnu99 for the host but [effectively] -std=gnu89 for
Windows.

The list of migrated libraries is currently empty. Libraries will be
migrated as follow up patches.
Test: Migrated libc to this system and everything still builds.
build.ninja shows libraries being built and used and headers are

Add SYSTEM_ to variables that contain headers that are used with
-isystem, and split -I and -isystem variables into separate make
variables. Also export SRC_HEADERS and SRC_SYSTEM_HEADERS to compare
against make.

Soong's multi-architecture building has grown complex, with the
combination of HostOrDevice+HostType+Arch necessary to determine how to
build a variant of a module, and three separate mutators to split each
into its variations.
Combine HostOrDevice+HostType into Os, which will be Linux, Darwin,
Windows, or Android. Store Os+Arch as a single Target.

Some more common makevars methods were required in order to remove the
"-isystem" prefixes from the toolchain.IncludeFlags() value. In Make,
the -isystem is prepended at time of use, not in TARGET_C_INCLUDES
itself.

This better matches the order from cc/cc.go, so that any implicit
ordering behaves the same in Make and Soong.

Static_executable was still using ModifyProperties, and was otherwise
missing things. Fix all of that up, and implement HostStaticBinaries,
which is the equivalent of BUILD_HOST_static in Make. That will default
host binaries to be static, which is useful for building SDK tools to
run with incompatible C libraries.

We don't ship binutils on Darwin, so there is no point in telling clang
to look in that path. (The path being used doesn't even exist). This
matches the Make behavior.

For configuration like TARGET_GLOBAL_CFLAGS, it would be good to have
Make and Soong use the same values. This change adds an interface for
packages like cc to verify the current value of make variables match the
Soong equivalents, and once they're satisfied with the results, remove
the make definition and use the value from Soong.
The cc implementation exports a few variables currently that I expect to
match between both implementations in all cases. It also checks
{CLANG,}{HOST,TARGET}_GLOBAL_{C,LD}FLAGS, which should be mostly similar
between make and soong now.
