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.

`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.

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

This provides a type-safe way for an action to express that it wants to be
called only once, or to capture move-only objects. It is a generalization of
the type system-evading hack in ByMove, with the improvement that it works for
_any_ action (including user-defined ones), and correctly expresses that the
action can only be used with WillOnce. I'll make existing actions benefit in a
future commit.

When built with `--define=absl=1` under Bazel, GoogleTest
flags use ABSL_FLAG instead of GoogleTest's own implementation.
There are some minor behavior differences in this mode.
The most notable difference is that unrecognized flags result
in a flag parsing error, and are not returned to the user though
a modified argc/argv, unless they appear after the positional
argument delimiter ("--").
For example, to pass a non-Abseil flag, you would have to do
./mytest --gtest_color=false -- --myflag=myvalue
The documentation at https://abseil.io/docs/cpp/guides/flags
may be helpful in understanding the behavior.
There are some other minor differences. For example,
passing --help results in the program returning 1 instead of 0.

A few tests are examining code locations and looking af the resulting line
numbers to verify that GoogleTest shows those to users correctly. Some of those
locations change when clang-format is run. For those locations, I've wrapped
portions in:
// clang-format off
...
// clang-format on
There may be other locations that are currently not tickled by running
clang-format.

This catches when a client creates an action and discards it, thinking that the action has actually been applied to something.
This will help people who make the mistake of defining, for example, both `void Use(Foo*, Bar)` and `ACTION_P(Use, bar) { Use(arg, bar); }` for later application to a Foo. With such an overload, a client may then write `Use(bar);`, selecting the Action<> overload and being confused why nothing happens.
This also catches when a client defines their own action in terms of an ACTION_P()-generated one, invokes the Action<>'s builder, and then fails to invoke the resulting action, thinking it's operating on the outer action's parameters.

They were all removed in #2815, but it looks like this one got added
from a Google export which missed the update. See #2815 for reasons why
removing this is desirable.
