Fix KCL source ranges to know which source file they point to

[jtran]

Fixes #4240. Addresses #4080.

When we display errors in a file, we need to know which source file it is pointing to. Previously, we assumed there was only ever one source file. A lot of code assumes that it can convert a Token to an error. So I decided to add the file to Token. But we also need the file specified in SourceRange in the AST Node for runtime errors.

In order to not cause a lot of overhead, the file path is interned (i.e. cached within a single run of the executor) and represented as the NewType ModuleId(u32).

0 always represents the top-level file that's executed, with imported files represented by other IDs. Before we send diagnostics to CodeMirror, we filter out anything that points to a file other than ModuleId(0). This is what fixes the editor to not lock up. See src/lang/errors.ts.
