Matthew Woehlke 37823b366f find_package: Restore component requirements in nested calls
Fix logic to populate required and optional components from CMake
variables when `find_package` is called in a nested context.

This was broken in commit e2a6416622 (find_package: Refactor in support
of recursion, 2024-11-29, v4.0.0-rc1~356^2), which promoted the
component sets from locals (in cmFindPackageCommand::InitialPass) to
member variables. Previously, in a nested context, these sets were
simply not filled, and we relied on the variables indicating component
requirement to already be set. When logic was added to properly fill the
sets (which is needed for CPS), it blindly dumped all components into
the required set, without actually checking whether the context had
marked the components as required or optional.

Fixes: #26824

CMake Tests Directory
*********************

This directory contains the CMake test suite.
See also the `CMake Testing Guide`_ and the `CMake Source Code Guide`_.

.. _`CMake Testing Guide`: ../Help/dev/testing.rst
.. _`CMake Source Code Guide`: ../Help/dev/source.rst

Many tests exist as immediate subdirectories, but some tests
are organized as follows.

* ``CMakeLib/``:
  Source code, used for tests, that links to the ``CMakeLib`` library
  defined over in ``Source/``.

* ``CMakeOnly/``:
  Deprecated.  Tests that run CMake to generate a project but not build it.
  Superseded by ``Tests/RunCMake/``.

* ``Find*/``:
  Tests for specific find modules that can only be run on machines with
  the corresponding packages installed.  They are enabled in
  ``CMakeLists.txt`` by undocumented options used on CI builds.

* ``Module/``:
  Tests for specific CMake modules.

* ``RunCMake/``:
  Tests that run CMake and/or other tools while precisely checking
  their return code and stdout/stderr content.  Useful for testing
  error cases and diagnostic output.

  See `RunCMake/README.rst`_.
