From T, apps need POST_NOTIFICATION permission
to send the notification.

-. Add the permission into Manifest.
-. Request runtime permission when it's needed.

Bug: 209479751
Test: Manual test as following steps:
      1. Open EditTextVariations at T device.
      2. Tap direct reply to send notification.
      3. Verify the permission dialog show up.
      4. Send the notification if permission granted.

With b/150232615, we will need an explicit value set for the exported
flag when intent filters are present, as the default behavior is
changing for S+. This change adds the value reflecting the previous
default to the manifest.

These changes were made using an automated tool, the xml file may be
reformatted slightly creating a larger diff. The only "real" change is
the addition of "android:exported" to activities, services, and
receivers that have one or more intent-filters.

This is a follow up CL to my previous CL [1], which enabled us to test
Direct-Reply with EditTextVariations.

What this CL does are:

 * Specyfing min_sdk_version to avoid INSTALL_FAILED_OLDER_SDK error
   when installing on older devices.
 * Avoiding NoSuchMethodError on pre-O devices where
   Notification.Builder does not have a constructor that takes
   notification channel.
 * Fixing a race condition where notification can be sent before
   notification channel is created.

Bug: 122957841
Test: Made sure that we can install EditTextVariations on N devices
      and "Direct-Reply" on EditTextVariations works there.
Change-Id: Ib4fbd447608b111e763fde4287226cf7e206e65e

With this CL, EditTextVariations is able to send Direct Repply
notification so that we can easily test IME behaviors there.

You don't need to set up a chat application then let it receive a
message from someone else any more just to test IME behaviors on
Direct Reply.

Fix: 122957841
Test: manually done as follows.
  1. tapas EditTextVariations
  2. make -j
  3. adb install -r \
     $ANDROID_TARGET_OUT_TESTCASES/EditTextVariations/EditTextVariations.apk
  4. Open EditTextVariations
  5. Tap the menu icon.
  6. Select "Direct Reply"
  7. Make sure that there is a Direct Reply notification.
