Fix malformed trace sections

In some scenarios, BiometricUnlockController#startWakeAndUnlock() may
have caused its parent's trace sections to end too early. Also, trace
all occurrences of "release wake-and-unlock", and rephrase trace section
for acquisition to use simple present tense for consistency and
succinctness, "acquire wake-and-unlock".

Test: Capture perfetto trace, inspect trace to verify all slices end
Flag: EXEMPT system tracing only
