Alex Rickabaugh b4b453d6de refactor(compiler-cli): make file/shim split 1:n instead of 1:1 (#38105)
Previously in the template type-checking engine, it was assumed that every
input file would have an associated type-checking shim. The type check block
code for all components in the input file would be generated into this shim.

This is fine for whole-program type checking operations, but to support the
language service's requirements for low latency, it would be ideal to be
able to check a single component in isolation, especially if the component
is declared along with many others in a single file.

This commit removes the assumption that the file/shim mapping is 1:1, and
introduces the concept of component-to-shim mapping. Any
`TypeCheckingProgramStrategy` must provide such a mapping.

To achieve this:

 * type checking record information is now split into file-level data as
   well as per-shim data.
 * components are now assigned a stable `TemplateId` which is unique to the
   file in which they're declared.
