The files generatd by `install(EXPORT)` and `export()` commands
are known to work with policies as of CMake 3.19, so enable them
in sufficiently new CMake versions.
The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.13 and below to encourage projects to port
away from setting policies to OLD.
Since commit 6a6f1d1edd (CTest: exit nonzero after
message(SEND_ERROR|FATAL_ERROR), 2020-04-03, v3.19.0-rc1~260^2), `ctest`
no longer runs tests if there are errors before the full set of tests is
defined. Such errors were previously treated more like warnings.
The change exposed some cases where we were issuing an error message but
proceeding to run tests anyway. The above commit downgraded one such
case (missing `DartConfiguration.tcl`) to a warning explicitly in order
to restore its former warning-like semantics.
Downgrade the Update step's diagnostic about modified or conflicting
files to a warning for the same reason.

Xcode 12 doesn't allow nested builds within the same build directory.
That means we can no longer do an install by building the install target
when IOS_INSTALL_COMBINED is true. We can, however, still do an install
by running the cmake_install.cmake script or executing cmake --install,
since there is no outer build and therefore the associated SDK can be
built as a sub-build.
The non-build methods previously didn't work when
IOS_INSTALL_COMBINED was true because the generated install script
and the CMakeIOSInstallCombined script both made certain assumptions
that relied on being part of a build. Those assumptions are now
removed. A side-effect of this work is that cpack now also works from the
command line when IOS_INSTALL_COMBINED is true.

In commit f034b0f663 (CMake compilation: do not use compiler extensions,
2020-03-14, v3.18.0-rc1~494^2) we explicitly defined `_POSIX_C_SOURCE`
to ensure availability of POSIX APIs even when compiler extensions are
not enabled. Update the code to avoid redefining `_POSIX_C_SOURCE` if
it is already defined. This occurs when building our release binaries
as configured in `Utilities/Release/linux`, where we define
`_POSIX_C_SOURCE` explicitly on the compiler command line.

When a framework is linked to a target by its full path and that
framework is located in one of the implicit framework search directories,
CMake 3.18.5 and earlier discarded that path.
ce2dee9e5b (Xcode: Don't add framework as -framework argument in
linker info list, 2020-09-28) introduced a regression which resulted in
the framework path always being added to the search path even if it
matched one of the implicit search paths. This broke the ability to do
device and simulator builds from the same configured project.
