This was accidentally removed when the command templates were
reorganized to introduce the new policy. Restore the flag in the shared
library creation to ensure that we emit the import libraries to the
correct location.

The helpers added by:
* commit 37bc3400cd (CMakePackageConfigHelpers: Add
generate_apple_platform_selection_file(), 2023-11-03)
* commit 4ac5a2f866 (CMakePackageConfigHelpers: Add
generate_apple_architecture_selection_file(), 2023-12-19)
were worded in terms of including package configuration files, but the
actual functionality is to include files *from* package configuration
files. The included files do not themselves need to be usable as
package configuration files.
Rename the options and clarify the documentation accordingly.

We represent stub libraries, e.g., for CUDA, using imported `SHARED`
library targets with only `IMPORTED_IMPLIB`, and no `IMPORTED_LOCATION`,
to indicate that the stub file is meant only for linkers and not dynamic
loaders. See commit 7351d590ee (cmTarget: Add a way to represent
imported shared library stubs, 2023-07-17, v3.28.0-rc1~344^2) and commit
fc6508921c (cmComputeLinkInformation: Restore soname lookup for
non-imported targets, 2023-12-05, v3.28.0~4^2).
If a shared library is linked to a stub, it has a `NEEDED` field
populated with the `SONAME` found in the stub. When a dependent target
links to such a shared library, some linkers want to find a library file
on disk and load it to see what symbols it provides. This is necessary
for linkers that enforce `--no-allow-shlib-undefined`. On hosts with
only the stub library installed, e.g., with only the CUDA toolkit
development package, the real runtime library corresponding to the
stub's `SONAME` may not even exist, so no `-rpath-link` flag can help
linkers find it. Pass the stub library to linkers explicitly so they
can find it without searching.

Since commit c26c6ac488 (Link Step: compute effective linker used by the
compiler, 2023-05-27) we used `UNKNOWN` if the linker id is not known.
This convention is not used elsewhere, and logic using the linker id
is easier when `if(CMAKE_C_COMPILER_LINKER_ID)` is false on unknown id.
`cmake_determine_linker_id` is only used for macOS because Apple device
platforms set `_CMAKE_FEATURE_DETECTION_TARGET_TYPE` to `STATIC_LIBRARY`,
but we might as well prepare for them anyway.
Previously we matched an entire build system output line and then
extracted the relevant portion in a separate brittle step. Match
it directly. Use the `CMAKE_LINKER` value directly if available.
We do not use `-Wl,-v` on SunOS because not all GNU deployments use the
`collect2` helper, and those that do do not always print the underlying
`ld` command line. Parse the `--with-ld=` option as a fallback.
When IBM XL is used as the host compiler for nvcc, it generates a
comma-separated link line. Parse the `exec:` line syntax separately, as
was done in commit b5f20da94d (CMakeParseImplicitLinkInfo supports comma
separated link lines, 2019-08-23, v3.16.0-rc1~181^2).
Xcode has been reported to not work at all with this when
ExternalProject projects share download files.
Revert commit 872daff159 (ExternalProject: declare byproducts for the
download step, 2023-09-21, v3.28.0-rc1~27^2) pending further
investigation.
Fixes: #25525
Since commit f73a5bfaa9 (UsePkgConfig: Replace exec_program() with
execute_process(), 2023-07-24, v3.28.0-rc1~321^2~6), trailing whitespace
was introduced into libraries linked, which violates CMP0004.
Previously `find_package(CURL COMPONENTS HTTP)` failed because the
`CURL_SUPPORTED_PROTOCOLS` variable returned by pkg-config is
a command-line fragment, but we need a semicolon-separated list.
