Use of -Weverything blocks build system changes and toolchain updates
on new warnings. Forbid it in the build system. Developers can
experiment with -Weverything on their module by adding it to their
Android.bp file and building with
m ANDROID_TEMPORARILY_ALLOW_WEVERYTHING=true

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).

The Customizer interface now provides a Flags method that takes a
CustomizerFlagsContext and can call AppendCflags to insert extra cflags
on a module.

This only translates the common case using $(LOCAL_PATH). If it doesn't
match here, Soong will throw an error with a suggested fix.

Some checks for common errors with user-provided compiler and linker
flags:
* Using -I instead of include_dirs
* Using -l<lib> in ldflags instead of host_ldlibs (or shared_libs)
* Using -L in ldflags
* Splitting a multi-word flag into two flags
* Combining two flags into one list entry
* Using a path that could search outside the source or output trees
* Using a non-whitelisted library in host_ldlibs
Maybe some of the flag checks should happen during a static analysis
pass, but we don't have one right now, and this only adds ~1/2 second to
our 73 second Mega_device runs (recompile the changed code, run
soong_build, then report unknown target).
