[Test] Break massive ios_test function into factory

Add the ability to override stuff.

Test rules were impossible to extend and difficult reasoning about how
it worked with rules_apple - which led to issues implementing new
features like shard by class.

Test rules simply accept a `test_suite_factory`. On the default one,
which you can override parts if necesary. _The default one could be much
generic - but at some point, I expect people to just make their own
`test_suite_factory` VS adding too many abstractions to it_

Last: normalize all into a single bundle - otherwise it would duplicate
tons of data and be un-useable at scale.

+Finally - you can set the splits to be whatever you want.
