Create a `self` parameter when importing a C++ non-static member
function. That seems to be all we need to get basic method calls
working! For now, `const` methods have by-value self parameters, and
non-`const` methods get an `addr self: Self*` parameter.
The none.carbon min-prelude is not just an empty prelude, it also
prevents any prelude from being imported at all. So no import machinery
runs before the test, only the `package` statement from the prelude
would run.
Use the none.carbon min-prelude in a few tests that were specifying
`--no-prelude-import` to give it a trial run.

All except
`toolchain/check/testdata/interop/cpp/function_param_int*.carbon` and
`toolchain/check/testdata/interop/cpp/function_return.carbon`.
Don't output SemIR for cases that are intended to fail.
This mirrors how imports work in general, that the imported declarations
shouldn't belong to the first referencing scope (particularly apparent
when referenced across multiple scopes). I think this was just an
oversight here.
People seemed receptive [on
#toolchain](https://discord.com/channels/655572317891461132/655578254970716160/1379196447827689553),
so proceeding.
For the two name conflicts, I've set it up so that there's a
"foo.carbon" and "foo_with_prelude.carbon", to indicate that the
no-prelude approach is preferred (with a shorter name).
Note min_prelude will require a little more work/thought, I want to
avoid adding `--custom-core` etc.
