Continuation of #21132. All uses of the `Uint32Array` view of the buffer in raw transfer code have been removed in preceding PRs. So we can now remove it entirely.
Refacfor. In a strange pattern, we were injecting `getNodeLoc` into `deserialize.js` module on every call to `deserializeProgramOnly`. It's a static function, so just import it.
Apply the same optimization as #19978 to comments - hold a pool of `Comment` objects, and re-use those objects rather than creating new objects each time.
Same as with `Token`s, `loc` property is a getter which calculates `loc` lazily, and caches it in a private property.
Previous raw transfer required that the source text start exactly at the start of the buffer. In linter, relax this restriction and handle when source text is stored elsewhere in the buffer.
This is necessary for stripping BOM from source (#18376), as then the source text used on JS side starts 3 bytes after the start of the buffer.
