This deprecates the PNG_VERSION_STRING result variable.
Additionally, the documentation has been adjusted and synced with other
similar find modules:
- Added "Deprecated Variables" section and deprecated versions.
- Added intro code block how to use this module.
Issue: #27088
The historic implementation of `$<CONFIG>` had some errors that could
result in multiple configurations matching. First, it always considered
the configuration of the consuming target, even if a consumed imported
target selected a different configuration. Second, it matched the entire
list of `MAP_IMPORTED_CONFIG_<CONFIG>` configurations, even if none of
those were actually selected. The latter in particular is redundant at
best, as we also consider the selected configuration of an imported
target, which is the correct configuration to match for imported
targets. Refactor the implementation so that only one configuration is
considered.

Issue: #27022
Commit 910ada1a88 (Genex: $<CONFIG:> syntax of all entries checked,
2023-01-17) tweaked how ConfigurationTestNode::Evaluate validates its
arguments, which resulted in the removal of the body of an `if` but not
the `if` itself. Since the condition does not have side effects, this
resulted in superfluous leftover code. Remove this.

As mentioned in the previous commit, we would like to record additional
information in the find-package stack, but we don't have the information
at the point a stack entry is created. This necessitates making the
stack mutable. However, in order to restrict mutation, do not directly
expose the mutable value, and instead arrange for it to be accessible
only via cmFindPackageStackRAII (renamed and extracted from cmMakefile).
This ensures that mutation can only happen while the stack is being
built.
We would like to record additional information in the find-package
stack, but we don't have the information at the point a stack entry is
created. The most sane way to handle this appears to be making the stack
mutable, at least under specific circumstances. To facilitate this, we
need a mutable stack type.
Refactor cmConstStack into cmStack, with the ability to either allow or
forbid mutation of its data. Re-add cmConstStack as a type alias.
This doesn't yet allow mutating cmFindPackageStack, but it's a necessary
step toward being able to do so.
This deprecates the ALSA_VERSION_STRING result variable, which was
previously documented up to CMake 3.11 and then removed from the docs
due to refactorings.

Since it can be set in the environment when running the test suite,
guard tests which are sensitive to intermediate directory strategy
changes with explicit settings.
Revert commit b70ef48b27 (install(DIRECTORY): Add
EXCLUDE_EMPTY_DIRECTORIES option, 2025-04-20, v4.1.0-rc1~212^2).
The implementation had at least two problems:
* It did not exclude the top-level directory if empty.
* It did not exclude non-empty directories whose contents are
all filtered out.
Revert the feature pending a revised implementation.
