Integrate JS parser module better with JRT

The fact that the JS parser had been developed as a separate
component for a while is still visible from some macros that mirror
things from JRT. This patch removes those duplicates and makes the
JS parser rely on jrt.h. (The removed macros are: `PARSER_DEBUG`,
`PARSER_INLINE`, `PARSER_NOINLINE`.)
