glsl: Switch from the deprecated YYLEX_PARAM to %lex-param.
YYLEX_PARAM is no longer supported as of Bison 3.0. Instead, the Bison developers recommend using %lex-param. %lex-param takes a type and variable name, similar to %parse-param, so you can't pass an arbitrary expression like state->scanner. But Flex insists on passing the actual scanner object, not an arbitrary object like state. To solve this, the parser defines a wrapper lex() function which accepts "state," and calls Flex's lex() function with state->scanner. Fixes the build with Bison 3.0. Also works with Bison 2.7.1.
