Collect metrics on running Accessibility services on Android

We'd like to optimize accessibility by only enabling the features actually
needed by running accessibility services. In order to determine what would
be the best signals of what running accessibility services actually need,
add some code to collect metrics on running accessibility services that we
can analyze later.

Manually verified that TalkBack, Select-to-Speak, and LastPass all result in
very different sets of metrics being collected.
