Allow interleaving of STDOUT and STDERR check lines. Put STDOUT lines
after the line they're attached to, and STDERR lines before. If no
STDOUT check line is attached to any line, then put them all at the end
of the file instead.
This is intended to better handle the case where stdout contains
unreplaced mentions of line numbers, and also reflects that stdout is
typically a consequence of the test rather than commentary on it, so
placing it after the test seems likely to read better.
This PR renames parse nodes on a Name/NameExpression taxonomy. NameExpressions occur in a name context. The difference is that in non-expression contexts it's useful to return the identifier / string ID for adding to name lookup, whereas in expression contexts it's useful to return the resolved node ID for consistency with other expressions.
In the code, I do note SelfValueName is returned in the expression context: I'd expect this to change, as `self` in `[self: Self]` versus `self.Foo()` will probably be best handled similarly to the above. That means that, in the proposed taxonomy, both `SelfValueName` and `SelfValueNameExpression` will exist in order to assist semantics.
To contrast choices:

NameReference | NameReference | NameReference | NameExpression
SelfValueIdentifier | SelfValueIdentifier | SelfValueReference | SelfValueName
SelfTypeIdentifier | SelfTypeIdentiifer | SelfTypeReference | SelfTypeNameExpression
This is just a simplification: I think these different forms are getting in the way more than they're helping, particularly as I was looking into namespace functionality. The handling in semantics can be identical, providing a more uniform behavior.
This builds on #2814 by adding the test framework to the toolchain. On Linux, this is 7s -> 4s for me. #2811 has more detailed timing for the explorer, which also had more dramatic changes because it's about 3x more tests run in 2x as many ways (6x total).

This makes it possible to specify both deduced and regular parameters on types. It reorganizes the handling of parameter lists in order to allow more reuse of code in this approach. Both functions and types use the new DeclarationNameAndParams handling. Overall the goal here is to take advantage of commonality in structure.
Regarding destructors, the likely approach would be to use ParameterListAsDeduced directly because `destructor` is a keyword with no declaration name and no regular parameters.
