runtime(javascript): fix a few issues with syntax higlighting
It addresses the following issues:
- Fix highlight of let and var javascript keywords
According to runtime/doc/syntax.txt, Identifier is for variable names.
let/var are not variable names, they are keywords
- Add highlighting for "from" keyword in javascript
- Fix highlight of function keyword in javascript
According to docs, Function is for function names, so the function
keyword should just be Keyword.
- Fix highlight of static keyword in javascript
According to vim docs: StorageClass static, register, volatile, etc.
