Make it so that `export`/`unexport` are deprecated during product
configuration, but obsolete during Android.mk parsing (and later in the
build, since we can't un-obsolete it).
Remove some ccache / goma exports, those don't need to be exports, since
soong_ui asks about them explicitly. They also only run doing the
initial project configuration, so we don't run anything with that
environment.

Our binary was rather old, and for a variety of reasons we haven't kept
it updated. We've been running into a handful of reliability issues that
would have been fixed with an update, and a few reproducibility /
correctness issues that may or may not be fixed with newer versions.
For local no-change full rebuilds, ccache can still save ~35% of the
build time (but adds a few minutes to initially populate the cache). But
most local uses should be using incremental builds anyways, not clean
rebuilds. Or you're doing builds of different configurations, which
wouldn't be cache hits either, and would make your cache even larger.
At a large scale, we haven't seen a significant performance difference
between having ccache on or off. This may be different if you've got
very good build locality, or a very large cache -- but if you've got
good build locality, it's reasonable to do incremental builds (not for
release builds, and while running `m installclean` in between builds).
So for our cases, we'd prefer the stability and correctness of not using
ccache, but if you still want to use ccache, continue setting USE_CCACHE
and also set CCACHE_EXEC to the path of your ccache executable.

This patch allows usage of a custom CCACHE_COMPILERCHECK setting
for the special cases when "content" strategy is not enough to ensure
that results retrieved from the cache are accurate for the current
compiler.

Instead of using recursive make to change the HOST_OS when building the
windows SDK under linux, add the concept of cross-building to another
host os.

- Don't overwrite [TARGET|HOST]_[CC|CXX] with the [CC|CXX]_WRAPPER prefix,
so that we can disable the wrapper per module.
- Disable ccache on a module when FDO is enabled.
