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.

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.

The way temporary directories were discovered from
environment variables in different operating systems
was inconsistent.
On Windows, only the system-specific environment variable
TEMP was considered, but not the bazel-common TEST_TMPDIR.
On Unix, only TEST_TMPDIR was considered, but not
the otherwise typical system specific TMPDIR.
Now, always consider TEST_TMPDIR first, followed by the
system-typical environment variable (TEMP on Windows, TMPDIR on Unix)
before falling back to a default on that particular system.
Also: the value for the temporary directory coming from the
environment variable was only checked for a trailing directory
separator on Windows (and appended if needed), not on the other
platforms.
Make this also consistent accross the systems: Now always apply
the same logic to all of these (to accomodate
tests that just concatenate TempDir() without directory separator).

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.

Currently MacOS falls back to generic /tmp, but
for all intents and purposes it should behave like
other Unixes using the TEST_TMPDIR environment variable
if available (this environment variable is set in bazel,
which sets up a unique temp directory for the test
process).
While at it, remove an incorrect #endif comment, that
looks like a leftover from some older implementation.

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

bazel build --define=absl=1 ...
A dependency on RE2 is now required when building GoogleTest with Abseil.
Using RE2 will provide a consistent cross-platform regex experience.
Users will need to add the com_googlesource_code_re2, bazel_skylib,
and platforms repository to their WORKSPACE files. See our WORKSPACE
file in the root directory of this project for an example of how to
add the dependencies.
Please note that the com_googlesource_code_re2 dependency must use a
commit from the `abseil` branch of the project:

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.
