Add ANR Specific Subreasons to AppExitInfo

This update introduces specific ANR subreasons to the
ApplicationExitInfo subreason list. Additionally, TimeoutRecord is
modified to correlate its TimeoutKind with a corresponding
ApplicationExitInfo ANR subreason. The subreason is then passed to
ApplicationExitInfo objects when the system identifies an unresponsive
app to be used by apps for further analysis.

This change does not populate the ANR subreason when the user kills the
app from the ANR dialog.
