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).
iOS/tvOS app bundles are flat and do not include the `Contents/MacOS/`
layers, so they should not be in the `IMPORTED_LOCATION`. Use the same
logic that commit 34f5ef564a (iOS: Fix App Bundle layout, 2015-12-10,
v3.5.0-rc1~129^2~1) added for the installation layout.

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.

Print an error message for invalid values of
`CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION` in a ctest dashboard script.
The option was added by commit 140704d443 (ctest: add option for
output truncation, 2022-03-07, v3.24.0-rc1~513^2).

We've made several attempts to add a dummy symbol to `mocs_compilation.cpp`
when there are no automoc sources:
* commit 4a9daae483 (automoc: silence linker warning on macos,
2022-05-25, v3.24.0-rc1~55^2)
* commit 844244ccdc (automoc: avoid compiler warnings in linker-warning-
silencing code, 2022-08-10, v3.24.1~6^2)
* commit fc8628389f (automoc: avoid more compiler warnings in linker-
warning-silencing code, 2022-08-29)
The last attempt derives a symbol name from the path to the source
file, but that breaks reproducible builds because it is not stable
w.r.t. the location of the build tree. Revert all these attempts
for the 3.24 release series, and return to what 3.23 and below did.
Further investigation will be needed to resolve the original issue.

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.
Add a cross-platform wrapper over mkdtemp. This will allow us to create
guaranteed-unique directories. On POSIX platforms, this is simply a
wrapper over mkdtemp. On Windows, we take a brute-force approach using
C++11's random facilities and relying on attempts to create an existing
directory resulting in an error. (This approach is very possibly how
mkdtemp is implemented internally, and should be suitable for any
platform if needed, although at present it only uses a partial set of
substitution characters since Windows likely implies a case-insensitive
file system.)
