SF: Add trace section flags and InputWindowInfo to sf trace

Trace section flags allow users to specify sections of the trace to be collected. By default, all
sections are collected. Options are:
  TRACE_CRITICAL - adds data critical for debugging
  TRACE_INPUT - adds InputWindowInfo
  TRACE_EXTRA - adds non essential data (metadata, derived data)
  TRACE_ALL - includes all sections (default)

To set the trace flags from shell:
$ adb shell su root service call SurfaceFlinger 1033 i32 <trace_flags>
