KWSys's `CollapseFullPath` no longer looks up the actual case on disk.
Add the lookup explicitly where we need it:
* `ToNormalizedPathOnDisk`
* `file(REAL_PATH)`
* `get_filename_component(... ABSOLUTE)`
Fixes: #20214
The linker configuration file is now optional: It is loaded only if
variable CMAKE_<LANG>_USE_LINKER_CONFIGURATION is set to TRUE.
The file CMakeAddNewLanguage.txt is updated to take into account the
linker configuration.
Fixes: #26393
Add documentation to clarify that `find_package` searches paths in the
specified order and stops at the first match. Clarify documentation of
`CMAKE_FIND_PACKAGE_SORT_*` to match the actual behavior.
Note that no behavior is actually changed, this merely improves the
documentation to reflect actual behavior rather than seeming to imply
something else.
Also, update the test to verify that what we claim in the updated
documentation is what's actually happening.
Extend discussion of the ``PRESERVE_ORDER`` example to prominently
explain how platform-specific behavior can affect generated link lines.
Closes: #26388

`CollapseFullPath` has two use cases:
1. Normalize input paths from command-line arguments and environment
variables. On Windows, load their on-disk capitalization.
2. Simplify paths constructed internally. These should already have
the correct capitalization.
Audit all `CollapseFullPath` call sites and code paths leading to them.
Replace those calls that normalize input paths with calls to
`ToNormalizedPathOnDisk` to express that they need the on-disk case.
By making this distinction we will later be able to remove the on-disk
capitalization lookup `CollapseFullPath`, thus eliminating disk accesses
from internal path processing.
Issue: #20214
`CollapseFullPath` currently accesses the filesystem on Windows to
convert the path to the (upper/lower) case it has on disk. Not all call
sites need this, so we'd eventually like to remove the behavior. Add a
wrapper for call sites to express that they need to match the case of
on-disk paths.

location where it doesn't make sense.
