Fixes https://github.com/flutter/flutter/issues/18014

* Remove uses of ReleaseOwnership from vulkan backend.

Flutter no longer needs to release ownership of objects to skia so this change removes the api calls.

* Remove Release call from vulkan_device.cc

* Update vulkan_application.h

* Update vulkan_application.cc

* Update vulkan_handle.h

This changes the ownership of the VkInstance and VkDevice back to the flutter's objects. I am trying to move skia into a world where GrVkBackendContext is purely a description of the vulkan context skia should use and is just passed in during GrContext creation. It shouldn't need to be ref counted or actually do work in destructor (those changes to come later). This is just a first step towards getting there.

A given character may render differently in various locales, and fonts on the
host system may be tagged with locale metadata in order to support this.
If the text renderer needs to find a fallback font for a character, it should
pass the preferred locale to Skia's font manager which can use it to find the
best matching font.

The font collection also needs to maintain different caches of fallback fonts
for each locale.

Eliminates the declaration that only arm64 is supported in
Flutter.framework's Info.plist. This causes Xcode's app thinning tools
to remove Flutter.framework in thinned archives for armv7 devices.

Although we do have a save before this SkAutoCanvasRestore so we
can theoretically send in doSave = false, it's safer to set doSave
to true to prevent future breakage.

As discussed with mtklein@google.com and reed@google.com, saving
canvas is very cheap in Skia so this should have no performance
impact. Skia is also considering remove doSave argument from
SkAutoCanvasRestore and always save the canvas.
