Let dumpstate also call "cmd input_method tracing save-for-bugreport"
This is a follow up CL to previous CL [1], which was to include
winscope tracing files from WindowManagerService into bugreport.
What this CL aims to do is also supporting InputMethodManagerService,
which is going to support winscope-compatible tracing protocol. With
this CL Dumpstate::MaybeSnapshotSystemTrace() starts calling the
following two shell commands:
cmd window tracing save-for-bugreport
cmd input_method tracing save-for-bugreport
On branches where InputMethodManagerService does not support the above
command, this CL will have no-op except for the following one-line log
will be seen in logcat.
02-20 00:56:30.754 root 5325 5325 E dumpstate: \
*** command 'cmd input_method tracing save-for-bugreport' \
failed: exit code 255
Like existing winscope tracing files, IME tracing files will be stored
in "/data/misc/wmtrace/" in the bugreport.
Here are upper limit of those tracing files.
ime_trace_clients.pb: 4MB
ime_trace_service.pb: 4MB
ime_trace_managerservice.pb: 4MB

Bug: 177462676
Test: Manually made sure as follows that wintrace log from
WindowManagerService is still included in the bugreport
if WMS supports "tracing save-for-bugreport".
1. adb logcat -d -s WindowTracing:*
Make sure wintrace is not yet running
2. adb shell cmd window tracing start
3. adb logcat -d -s WindowTracing:*
Make sure wintrace is running
4. adb bugreport bugreport.zip
5. adb logcat -d -s WindowTracing:*
Make sure wintrace stopped then restarted.
6. unzip -v bugreport.zip | grep wm_
Make sure "wm_{trace,log}.pb" are included.
