Replace our hard-coded defaults for `/MD` and `/MDd` with a first-class
abstraction to select the runtime library from an enumeration of logical
names. We've long hesitated to do this because the idea of "runtime
library selection" 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 flags 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 CMP0091 to provide
compatibility.

To manage the lifetime of `cmTargetInternals`, the private implementation of
`cmTarget`, use `std::unique_ptr<cmTargetInternals>` instead of
`cmTargetInternalPointer`, which is removed.
`cmTarget` is made non-copyable but movable.

The new optional `before` parameter in `cmTarget::AddSource` and
`cmGeneratorTarget::AddSource` allows to prepend a source file
to the sources list instead of appending it.
This adds
- the variable ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` which initializes
- the target property ``AUTOGEN_ORIGIN_DEPENDS``
which controls whether or not the origin target dependencies
should be forwarded to the corresponding ``_autogen`` target.
The default value of ``CMAKE_AUTOGEN_ORIGIN_DEPENDS`` is ``ON``
which corresponds to the behavior that is in place since CMake 3.9.
Closes: #18493
This makes binaries independent of the build directory by not embedding
the build directory via RPATH. The tests are partially based on the
existing RuntimePath test, but with the check moved into a POST_BUILD
command such that it can be skipped when the platform lacks support.

These new capabilities enable to manage link directories
Two new properties:
* target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES
One new command
* target_link_directories(): to populate target properties
Fixes: #17215
Previously the command did not allow naming targets on the LHS that
were not created in the calling directory. Lift this restriction to
enable more flexible use by projects.
Targets named on the RHS will need to be looked up during generation in
the scope of the call site rather than the scope of the LHS target.
Introduce an internal syntax in `[INTERFACE_]LINK_LIBRARIES` properties
to specify target names that need to be looked up in a directory other
than that containing the target on which the property is set. Add
minimal documentation of the syntax to help users that encounter it.
Unfortunately CMake previously did allow such calls in the case that
only `INTERFACE` libraries are specified, but those libraries would be
looked up in the target's directory rather than the caller's. Add
policy `CMP0079` to enable the new behavior with new lookup scope in a
compatible way.
Fixes: #17943
