Switch to the new SkSL lexer.
This completely replaces flex with a new in-house lexical analyzer generator,
which we have done for performance and memory usage reasons. Flex requires us
to copy strings every time we need the text of a token, whereas this new lexer
allows us to handle strings as a (non-null-terminated) pointer and length
everywhere, eliminating most string copies.
