Use a scoped helper class to push and pop CodeGenerator::fOut changes.
This mirrors other "AutoXxxxxxx" classes used in SkSL to push and pop
temporary changes into member variables, such as AutoSymbolTable or
AutoLoopLevel.
Metal and Pipeline code generators were updated to use this class.
SkSL was left as-is for now; it modifies fOut more extensively than the
others and will need special care.
