Update git submodules

* Update frameworks/support from branch 'androidx-master-dev'
  to 54b0c07b311750b9909983f640a9ba64f5f37cd6
  - Merge changes from topic "robolectric_4.4-alpha-2" into androidx-master-dev
    
    * changes:
      Remove unnecessary ternary operator from ExifInterface constructor
      Add ObjectsCompat#toString(Object, String)
      Remove unnecessary shadow declaration
      Update enterprise-feedback for Robolectric @LooperMode(PAUSED)
      Update camera Robolectric tests for @LooperMode(PAUSED)
      Update Robolectric dependency to 4.4-alpha-2
    
  - Remove unnecessary ternary operator from ExifInterface constructor
    
     Removes unnecessary private constructor to remove usage of ternary
     operator in constructor.
    
     This works around an issue that Jacoco has with instrumenting
     constructors with ternary operators inside a this() or super()
     statement (b/26641175)
    
    Bug: 162018163
    Test: ./gradlew test -Pandroidx.coverageEnabled=true
    Change-Id: I921a233ba43fdd260e4bb9728395c8a799c2c4a5
    
  - Add ObjectsCompat#toString(Object, String)
    
     ObjectsCompat#toString(Object, String) will return the second argument
     if the first argument is null.
    
     Uses this method to work around a bug in JaCoCo that occurs when
     'super()' includes a ternary operator in a constructor (b/26641175)
    
    Relnote: "Added ObjectsCompat#toString(Object, String). This offers the
    behavior of Objects#toString(Object, String) but can be used pre-API
    19."

  - Remove unnecessary shadow declaration
    
     ShadowPendingIntent is already part of Robolectric, so it will be used
     automatically. This seems to resolve an OOM error that occurs in
     CustomTabsIntentTest due to loading resources for API 29.

  - Update enterprise-feedback for Robolectric @LooperMode(PAUSED)
    
     Robolectric 4.4 now uses @LooperMode(PAUSED) by default. This requires
     changing the way we drive robolectric tests.

  - Update camera Robolectric tests for @LooperMode(PAUSED)
    
     Robolectric 4.4 now uses @LooperMode(PAUSED) by default, this requires
     a few changes to the way robolectric tests are driven.
