c576e93d17 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.

b5f3b656de Add missing stdarg.h include
This file makes use of va_list so it should include stdarg.h. This was handled
implictly by SkString.h before https://skia-review.googlesource.com/34381
landed.

634624a185 Micro optimizations to SkSL parser
Some of these are pretty trivial, but a few really moved the needle. In
total, this cut the time in the parser by about 10% in my profiling.

The early returns from peek and checkNext are probably the biggest wins,
everything else is mostly about cutting down on string copying.

93ba0a4fc8 Switch SkSL to std::string
On desktop, this saves just over 5% of the time in the SkSL compiler.

As written, the code will now build either way, so it's much easier to
switch back (or even have some platforms use SkString, if that's ever
required).
