Restrict what activity launches show permission prompts

Only show a permission prompt if the activity is a launcher, the calling
app is the same as the opened intent app, or the
isEligibleForLegacyPermissionPrompt ActivityOption is set. Also prevents
the dialog from showing while the keyguard is locked.
