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 new sub-command writes a string representation of the
current log level to the output variable given to the
sub-command.
Given that the log-level might be set either via the --log-level
command line option or via the CMAKE_MESSAGE_LOG_LEVEL
cache / regular variables, the priority for each of the log level
sources is as follows, with the first one being the highest:
1) --log-level
2) CMAKE_MESSAGE_LOG_LEVEL regular variable
3) CMAKE_MESSAGE_LOG_LEVEL cache variable
4) default log level (STATUS)
Fixes: #23572
Move LogLevel enum into the cmMessageType.h header in preparation
for a new log level querying feature.
Wrap the enum into a new Message namespace.
Adjust all code usages.
Rename the booleans 's_ErrorOccured' and 's_FatalErrorOccured' to
's_ErrorOccurred' and 's_FatalErrorOccurred', respectively.
Rename the getters and setters to 'Get[Fatal]ErrorOccurred' and
'Set[Fatal]ErrorOccurred', and fix all uses across the codebase.
Allow FetchContent_MakeAvailable() to try a call to
find_package() first, or redirect a find_package() call to
FetchContent_MakeAvailable(). The user can set variables
to control which of these are allowed or tried by default.

The fix in commit e4f1b301fe (cmake: Allow arbitrary args passed to
CMake script, 2020-05-04, v3.18.0-rc1~211^2) only applied to "cache"
arguments like `-DFOO`. Extend the fix to allow arbitrary arguments
that collide with other CMake arguments like `-S` and `-B`.

When given two source paths via `-S` or just directory paths prefer
the last one. When the paths are mixed always prefer the last `-S`
entry.

Tools using the json-v1 format might want to trace stack frames across
different `CMakeLists.txt` files, in order to, for example, provide
stacktraces that span from the top-level `CMakeLists.txt` in a
project. One would think that `frame` lets you do that, but it
doesn't, because it tells you the depth of the stack within the
current `CMakeLists.txt`, so it gets reset across calls to
`add_subdirectory`.
The solution involves adding a field with a "global frame". This value
gets incremented on calls to `add_subdirectory`, which makes it easier
for tools to reconstruct "global stacktraces".
I considered changing the current "frame" value, but I didn't because
it would be a breaking change. I cannot think of any use-case where
"frame" is more useful to "global-frame", but maybe I'm missing
something.
When cmake parses `cmake -S <path> <path>` treat the second
path as the build directory. Likwise when invoked with
`<path> -S <path>` treat the first path as the build path
instead of using the current working directory.
Add a `--debug-find-pkg=` option to debug find calls for specific
packages.
Add a `--debug-find-var=` option to debug find calls for specific
return variables.
Fixes: #21880
Move backtrace printing functions from `cmListFileBacktrace` over to
`cmMessenger`, their primary caller. Thread `cmMessenger` instances
through APIs needed to update other call sites.
