Add the AndroidUnwinder objects.

Create two different objects (AndroidLocalUnwinder and
AndroidRemoteUnwinder) that encapsulate all Android related
knowledge. This makes it simple for other code to create one
of these objects and not need to add all of the Android specific
code themselves.

Add new unit tests to cover these new objects.

New unit tests uncovered a small bug in the Unwinder object, namely
that if you are skipping libraries, the suffixes to ignore still
looks at the ignored frames. Fixed to only apply ignore suffixes to
only non-ignored frames.

Rewrote all of the places that attach to remote processes and
created a single function to handle all of the different cases.

Bug: 120606663

Test: All unit tests pass.
Test: Ran the tests hundreds of times on host and target.
Test: There are still some failures, but only 1 in 800 and 1 in 300.
