[stdlib]: Add an android.oom_adjuster module

android_oom_adj_states contains a row per oom_adj transition in all
processes. The transition is augmented with metadata about the last
oom_adj update in the system_server. Furthermore, we also expose
a generic oom_adjuster translation function.

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