perf(transformer): React JSX reduce allocations

[overlookmotel]

React JSX transform was creating CompactStrs (which can involve heap allocations) and then converting them back to Atoms to insert into AST.

This PR removes the intermediate CompactStrs and allocates strings directly into the arena without intermediate heap allocations.

In case you're is wondering why I'm bothering making these fairly small optimizations, this is just tidying up the code while I'm going through it figuring out the scopes stuff.
