Update the --debug-trycompile documentation to account for recent
changes to try_compile. Mention where in the build tree to find
artifacts when using said option.
Add ability to copy try_compile (and try_run) source files from
arbitrary locations into the operation directory. This is included for
the sake of completion and consolidation, although use cases which
actually require this may be rare.
Add ability to "feed" try_compile (and try_run) sources more directly,
either from literal content, or from a CMake variable which contains
literal content. This saves the user from needing a separate step to
write the content to a file, and allows for the sources to only exist in
the scratch directory.

Apply the change from commit 00b788e85e (Help:custom_command: link
policy on BYPRODUCTS, 2022-09-09) to `add_custom_target` docs too.
Issue: #23786
Introduce a new signature for the project flavor of try_compile (and
try_run) which removes the `bindir` argument and adds a required PROJECT
tag. This is similar to the SOURCES flavor added by commit aa9220d3
(try_compile: Add keyword-dispatched signature, 2022-09-02).
Replace our hard-coded default for `/Zi` with a first-class abstraction
to select the debug information format an enumeration of logical
names. We've long hesitated to do this because the idea of "debug
information format" touches on related concepts on several platforms.
Avoid that scope creep by simply defining an abstraction that applies
only when targeting the MSVC ABI on Windows.
Removing the old default flag requires a policy because existing
projects may rely on string processing to edit them and choose a
runtime library under the old behavior. Add policy CMP0141 to
provide compatibility.
Fixes: #10189
Introduce a new signature for try_compile (and try_run) which removes
the `bindir` argument and requires the SOURCES tag. This will eventually
allow us to add other ways of providing sources, but also allows us to
change the behavior without breaking compatibility.
The old signature uses a special, but non-unique temporary location
inside the specified `bindir`, which conventionally is just the
project's build directory. The new signature unconditionally uses the a
unique temporary directory which is unconditionally within the project's
build directory (which is no longer separately specified). This ensures
that successive runs do not overwrite previous runs, will simplify
debugging, and should also, eventually, allow us to execute multiple
trials in parallel.

The docs for if(PATH_EQUAL) did not mention the component-wise
nature of the checks. It also claimed no normalization was
performed, but multiple separators are effectively collapsed
(part of normalization). Improve the wording to clarify both of
these points.
Also update the corresponding description of cmake_path(COMPARE),
which had the same inaccuracy.
