In the `cmake` command-line tool, the `message()` command with no
message mode argument prints the message stderr using the C++ `cerr`
stream. Since commit 0a0a0f8a74 (cmMessenger: Color messages to
terminal by type, 2021-05-18, v3.21.0-rc1~146^2) and an update by
commit c7a8c9c811 (cmMessenger: Revert to non-color messages on
Windows, 2021-07-20, v3.21.1~15^2), we print the newline at the end of
the message using just `\n`. We've now observed some cases of output
on stdout and stderr getting jumbled when the two go to the same file
descriptor. Previously the newline was printed with `endl`, which
implicitly flushes. Flush explicitly to restore that behavior.

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
Since commit 0a0a0f8a74 (cmMessenger: Color messages to terminal by
type, 2021-05-18, v3.21.0-rc1~146^2) the message output no longer goes
through our custom streambuf on Windows that converts output encoding.
This can cause messages to be printed with the wrong encoding in a
Windows Console. It also causes messages to have a mix of LF and CRLF
newlines because `stderr` converts LF to CRLF but our custom streambuf
does not.
Revert to using just `cerr` for messages on Windows. Another approach
will be needed to achieve color output on Windows later.

Documentation added by
* commit 4f4f2028b8 (Help: Add documentation for buildPresets and
testPresets, 2021-01-13, v3.20.0-rc1~51^2~7)
* commit 676ecf0d37 (cmake-presets: Add build and test presets,
2020-12-14, v3.20.0-rc1~51^2~6)
used square brackets in the `cmake --build` signature to indicate
non-optional alternatives, which is not a typical convention.
A common convention is to use parentheses instead, but in this
case it is probably clearer to list the two signatures separately.

If a path argument with no -S or -B leads to a cache directory,
use that directory as the binary directory. Otherwise, use the
binary directory from the preset.

This option has been broken since commit b9f9915516 (cmMakefile: Remove
VarUsageStack., 2015-05-17, v3.3.0-rc1~52^2). That commit removed the
check that an initialized variable has actually been used and caused the
option to warn on every variable ever set. This was not caught by the
test suite because the test for the feature only checked that warnings
appear when needed and not that they do not appear when not needed.
The option was never very practical to use. Remove it to avoid the
runtime cost of usage tracking and checks for every variable (which we
were doing even when the option was not used).
This commit addresses two sources of build errors when using the warning
flag -Werror=unused-function for GCC in the default compiler flags.
The affected functions are not used when building in bootstrap
mode and therefore should be ifdefed out.
No functional changes.
For users of CMake who want to optimize their scripts if they take a
while to run, this commit adds the ability to output profiling data.
To enable this output, it adds the two command line parameters
to select the output path and format.
This commit adds the first profiling format of type ``google-trace``,
which is the output is a JSON file containing Duration events as per the
Google Trace Format specification:
