These targets use symbols from some shared libs that happens to be
re-exported by one of the static libs in non-LTO mode. ThinLTO is more
aggressive/accurate at pruning unused symbols, thus the build fails due
to missing symbols.

Fixed by explicitly listing the dependent shared libs.

Ran a sed rule to replace most instances of //bt to //bt/system in all
BUILD.gn and *.gni files. Also made some manual changes to include
directories using packetgen and dumpsys to include bt/system/gd instead
of just bt/gd. Added a new BUILD.gn at root that just points to
system/BUILD.gn.

On the Rust side, updated the Cargo.toml paths and build.rs includes for
topshim.

This reverts commit ddd429fe.

As it turns out, we will need to change //bt to //bt/system after all
because the ChromeOS ebuild can't easily handle the subdirectory change
otherwise.

Phonak does not adjust volume with the level included in set absolute
volume command. Disable absolute volume control for Phonak to avoid
volume keep at max.

Cargo was not rerunning build.rs for linking when there were new C++
libraries available. This adds a rerun-if that checks the C++ output
directory for changes when making this decision.
