I love this.
I only ever had to do a handful of a new completion/tooltip tests, but the test setup with the repetitive line of code entry, and having to manually adjust coordinates, was very annoying and hard to one-shot correctly.
I also believe the {caret} DSL now with the boilerplate removed will be easier for use also for non-humans :))

This PR replaces the manual context creation with locating a
{caret}mark in the source in more tests. It makes it much easier to write new editor-related tests and should also prevent mistakes that are easy to make when providing the context by hand. It continues the work started in #18524 and #18609.To make it easier to use the FCS APIs it introduces several new types:
SourceContext: contains info about the cursor position and the line textResolveContext: contains data needed for resolve-related features (getting a symbol, tooltip, overloads, etc)CodeCompletionContext: similar toResolveContextbut has code completion-specific differencesIt also introduces new
Checkermodule that provides test helpers for working with these new contexts. We may evolve these helpers into a newer FCS API in future, as it makes it significantly easier to work with these contexts than to provide things like the cursor coordinates separately.
