This applies commit 88441bfc0f712ad451784851bfcf0b0cc418ad75 from the
skia_rev_130a118cc68f8f9973e9572356011de378463fea branch to master so
master works in the Fuchsia build again.

Previously we had passed a local generator to flow::BitmapImageCreate /
SkImage::MakeFromGenerator, which takes ownership of the generator.
That generator in turn referenced an SkData backed by a local vector.
The result was an SkImage backed by a deleted buffer.

Merged iOS and Android font fallback mechanisms and push font discovery logic into skia

Provide a default status bar tap handler for FlutterAppDelegate.
By default, taps are passed to the key window's rootViewController if
it's a FlutterViewController. Apps with custom app delegates can
customize this behaviour to send the tap to the FlutterViewController(s)
they prefer by overriding touchesBegan:withEvent.
