chore: remove handle_compile_error

[Rich-Harris]

noticed while working on #11627 — we don't need the awkward handle_compile_error stuff any more, because the relevant information now lives in state.js. I haven't removed the function calls yet in this PR because that would cause annoying conflicts — will finish it off once that PR is merged

• add location info inside CompileError constructor
• remove unnecessary try-catch in compile/compileModule/parse

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• Prefix your PR title with feat:, fix:, chore:, or docs:.
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests and linting
