[stdlib] Improvements to experimental_slice_flattened

This table was introduced in Id63fbc407fbc8bc9fff12f7bc102eeccfcfd8381.

This change improves the query performance by avoiding a JOIN with
ANCESTOR_SLICE.

It also skips instant events from the 'flattened' slices.

Lastly, we move this to a new module 'flat_slices' to not regress the
load performance of the more commmonly used 'slices' module.

Test: Test: tools/diff_test_trace_processor.py out/android/trace_processor_shell --name-filter '.*slice_flattened.*'
