Zachary D. Rowitsch 070391daaf Add JavaScript template literal support with string interpolation ...

Template literals (`hello ${name}`) are the last Tier 1 blocker before
shimming Test262's assert.js/sta.js harness files. The tokenizer eagerly
scans each template into a composite token (quasis + raw expression
strings + absolute byte offsets), and the parser re-tokenizes expressions
with span rebasing for correct source locations. Includes UTF-8-safe
quasi string building, nesting depth limits, and structural comment
skipping in nested expressions.
