Refactor diagnostic errors to use miette.

This commit refactors the lexer/ast/resolution errors to be based on `miette`
and removes the custom error formatting implementation.

The relevant error types also no longer have a lifetime parameter and own the
data.

Test baselines have been updated to the new error format.

The `Span` type has been replaced with `SourceSpan` from `miette`.
