Add tests for `}` before `else` in `let...else` error

Change to explicit cases for expressions with optional values when being checked for trailing braces

Add tests for more complex cases of `}` before `else` in `let..else` statement

More expressions correctly are marked to end with curly braces

Fixes rust-lang#118859, and replaces the mentioned match statement with an exhaustive list, so that this code doesn't get overlooked in the future

fix: Overlapping spans in delimited meta-vars

Closes rust-lang#118786

Delimited meta-vars inside of MBE's spans were set to have the same opening and closing position resulting in an ICE when debug assertions were enabled and an error was present in the templated code.

This ensures that the spans do not overlap, whilst still having the spans point at the usage of the meta-var inside the macro definition.

It includes a regression test.

Constness in an item bound will be represented by an effect param, so no need to record constness here.
