Update supported iOS to 11

Skia bots build and test on iOS with a minimum of iOS 11. Chrome
currently requires 13 and other internal users are at minimum 11. While
Skia may currently build with older minimum targets (currently back to
iOS 8, though shortly will require iOS 9) it is not tested on versions
older than 11.

+------------
+  * Minimum supported iOS raised from 8 to 11. Skia may build back to iOS 9 but versions older
+    than 11 are not tested. Community contributions to support versions 9 and 10 of iOS may be
+    considered, but they may not be complex as they cannot be tested.
