Remove the MSVC pragmas for disabling warning C4717 (infinite recursion) for
Invalid<T>() because that warning has been fixed in cl/441474979.

Some Mock constructors insert the pointer to the Mock itself into a
global registry. Since GCC cannot see how the pointer is used (only as
an identifier), it cannot tell that the object doesn't need to be
initialized at that point at all. Work around this by using uintptr_t
instead.

This fixes unused parameter errors under both MSVC and clang (when
`-Werror=unused-parameter` is used, as reported
[here](9d21db9e0a (r74769946))).

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.

`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 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.
