The ability to disable adding architectures completely for packaging purposes
and cases requiring passing the architectures flags explicitly has been
requested.
Support a false value for CUDA_ARCHITECTURES and CMAKE_CUDA_ARCHITECTURES
for this purpose.
Implements #20821.
cc02ced530 find_program: Revert "Find programs that are executable but not readable"

Clang isn't very good at finding the installed CUDA toolkit.
The upstream recommendation is that we should pass the toolkit explicitly.
Additionally:
* Avoids Clang having to search for the toolkit on every invocation.
* Allows the user to use a toolkit from a non-standard location by simply
setting CUDAToolkit_ROOT. The same way as with FindCUDAToolkit.
Clang wants the directory containing the device library and version.txt as the
toolkit path.
We thus pass the newly introduced CUDAToolkit_LIBRARY_ROOT as the toolkit path.
We save CUDAToolkit_ROOT_DIR and CUDAToolkit_LIBRARY_ROOT on Clang to have them
available in try_compile() and avoid unnecessary re-searching or a possibly
different installation being found in FindCUDAToolkit.
This however means that the selected toolkit can't be changed after the initial
language enablement.
We now determine CUDA compiler ID before doing actual detection, as we don't
want to spend time finding the CUDA toolkit for NVIDIA.
Implements #20754.
The fix in commit 86e6349ef7 (find_program: Find programs that are
executable but not readable, 2020-04-04, v3.18.0-rc1~372^2) can break
existing projects that were (likely accidentally) relying on the
old behavior to find files that are readable but not executable.
Revert the fix for now. We can re-introduce it with a policy later.
Instead of reverting the test case, update it to cover the old behavior.
That can serve as a reference for testing the policy when introduced.

Issue: #10468
Refactoring in commit 3b547e2e4b (VS: Simplify logic adding source file
C/C++ language flag to MSVC, 2020-05-15, v3.18.0-rc1~139^2~1) failed to
account for MSVC's treatment of `.C` extensions as C. Add this special
case to the logic to restore use of `-TP` for `.C` extensions.

In commit b36d1bdd9d (Single location for cmProp typedef, 2020-05-30)
we accidentally left inclusion of `cmProperty.h` out of the main
block of includes.
Since commit e98588aaba (CUDA: Add CUDA_ARCHITECTURES target property,
2020-03-12), `CMAKE_CUDA_ARCHITECTURES` is both initialized and required
by policy CMP0104's `NEW` behavior. Inside a `try_compile` project we
use `cmake_minimum_required(VERSION ...)` with the current running
version of CMake. Now that our version number is 3.18, `CMP0104` gets
set to `NEW` in the `try_compile`. If the outer projects does not set
the policy then `CMAKE_CUDA_ARCHITECTURES` is not available and the
`try_compile` fails to generate.
Teach `try_compile` to check the outer project's policy status and
set policy CMP0104 to `OLD` if needed to match.

This makes them compatible with `VS_PACKAGE_REFERENCES` and, in
particular, fixes nuget package references in combination with install
targets.

VS 16.6 added a `StdOutEncoding` setting for custom commands to tell
MSBuild that the output is encoded as UTF-8. In commit bc877a7e94 (Add
support to indicate UTF-8 custom command pipe output encoding,
2020-04-08) CMake learned to add the setting in anticipation of the VS
16.6 release. However, when 16.6 was released it had a bug in the
implementation of custom tasks with StdOutEncoding enabled that was
exposed by our test suite. In commit 5058fb5401 (VS: Drop
StdOutEncoding with VS 16.6 pending investigation, 2020-05-29) we
disabled the setting pending investigation.
The problem is fixed in VS 16.7 Preview 3, so restore use of the
setting when a VS instance of at least that version is detected.
