Currently it will refuse to become a `OnceAction` if its component sub-actions
have an `Action` conversion operator but don't know about `OnceAction` in
particular because although `Action` is convertible to `OnceAction`, the
compiler won't follow the chain of conversions.
Instead, teach it explicitly that it can always be a `OnceAction` when it can be
an `Action`.

Ensure that tests are run in the order specified in the source code, even if
they are registered manually using RegisterTest. There should be no behavior
change for the common case.

This makes the behavior consistent when GTEST_STACK_TRACE_DEPTH is set to zero
and not: there is always vertical whitespace separating failure messages.

Do this by ripping out the "untyped perform action" machinery, which isn't
necessary: we can simply template the entry point on the result type, and use
RAII to avoid the need to special case void. This makes it easier to understand
the code and harder to introduce type-related undefined behavior, to boot.

Previously this excluded callables that return non-moveable types. This is the
same as the
[libc++ std::is_invocable_r bug](https://github.com/llvm/llvm-project/issues/55346)
fixed by
[this commit](https://github.com/llvm/llvm-project/commit/c3a24882903d): it's
wrong to use std::is_convertible for checking the return type, since (despite
its name) that doesn't check the standard-defined notion of "implicitly
convertible". Instead we must base the check on whether the source type can be
used as an argument to a function that accepts the destination type.

method to be templated on the action's result type.

`Return(x)` can now be used directly with `WillOnce` (the only place it makes
sense in the type system), without using `ByMove`.

It doesn't make semantic sense for the conversion to modify the input, and the
fact that it's allowed to do so appears to have just been a historical accident.

Better document requirements, API decisions, and historical accidents. Make an
implicit conversion easier and in a more appropriate place, and ease the burden
of some assertions in the conversion operator. Stop using the legacy
ActionInterface style for defining the action.

So that it can be referenced in conversion operators for actions that need to
know the concrete return type.

Rather than branching on whether the return type is ByMoveWrapper within
ReturnAction itself, hoist the distinction to outside. This allows the main
class template to be modified without worrying about this special case, which
means we can stop using a shared pointer to the value (introduced as a
linked_ptr in commit 3d1c78b2bf to support ByMove) in this commit and simplify
the class template further in a future commit with the eventual aim of directly
supporting move-only result types.

Commit a070cbd91c added an implicit cast to this path but didn't leave a very
clear explanation for why it was desirable, a clear example, or even test
coverage. Add a better comment and a test that fails when the implicit cast is
removed.

This is necessary for generic support of these actions, since `DoAll` is a
frequently-used action wrapper.
