[sf] Switch layer trace generator to use the new sf front end
Previously we used a mocked up flinger to playback the transactions
and then generate the layers trace. This was prone to data races
since layers were added on binder thread and transactions were
committed on the main thread. This would lead to invalid data
being generated or crashes.
This cl modifies the transaction traces to capture state changes
in the main thread and uses the new front end logic to generate
the layer snapshots. New front end has no dependencies to the rest
of surfaceflinger and will be more robust in recreating layer
snapshots .
Test: presubmit
Test: capture layers and transaction traces
