LibJS: Implement tagged template literals (foobar)

Browse source 
To make processing tagged template literals easier, template literals
will now add one empty StringLiteral before and after each template
expression *if* there's no other string - e.g.:

`${foo}` -> "", foo, ""
`test${foo}${bar}test` -> "test", foo, "", bar, "test"

This also matches the behaviour of many other parsers.
