Remove Metal support on older OSes.
SkSL now requires the array<> feature in MSL, so practically we no
longer support OS versions older than iOS 10.0 and MacOS 10.13. And
because of the shader compilation issues we are no longer testing nor
can we recommend running on MacOS 10.13, so this minimum version is
bumped up to MacOS 10.14.
