ea84dd9118 libtxt: extend Minikin to find a fallback font if its font collection can not match a given character (flutter/engine#4595) 
Minikin layout uses a FontCollection containing a list of pre-selected fonts
for a particular font family.  This patch extends the FontCollection to invoke
a hook provided by libtxt if layout sees a character that can not be rendered
by any font in the collection.

* Change the Minikin lock to a recursive mutex.  This is required because the
  fallback font provider may create new fonts during a layout operation that
  already holds the lock.
* Implement a fallback font provider hook that queries Skia for fonts matching
  an unrecognized character.
* Maintain a cache of fallback fonts.  Prepopulate the cache with fonts
  covering some commonly used character classes.
* Add a last resort font list for cases where Skia's font manager can not
  find any font for a character (similar to Blink's FontCache::getLastResortFallbackFont)

fa96568e15 Transition render target images before submit. 
Required by the spec; see '6.7.4. Queue Family Ownership Transfer'
of Vulkan 1.0.66.

Transitioning the image layout also fixes an image resolve failure
issue introduced by optimizations present in the intel mesa vulkan
driver v17.2.

This reverts commit d468d29a77.

Apparently the clang toolchain is still hitting issues. Will give this
another go after the next clang toolchain update.

d468d29a77 Use @available checks for iOS 11 features (flutter/engine#4596) 
Guard code that deals with iOS safe area insets behind an @available

This cleans up some old TODOs from before out clang toolchain supported
@available.

08f3598be8 Make Canvas cullRect optional and make Rect.largest a static field. (flutter/engine#4551) 
Fixes https://github.com/flutter/flutter/issues/7201.

The change from `new Rect.largest()` to `Rect.largest` saves a few
allocations since we'll be using these with every Canvas.
