Brad King 7afa58b15d Modules/Find*: Include FindPackageHandleStandardArgs normally
Since commit d74210a8bd (CMP0017: Remove support for OLD behavior,
2024-11-17) we can rely on CMP0017's NEW behavior unconditionally.
Calling `include(FindPackageHandleStandardArgs)` in a builtin module
will always get the builtin `FindPackageHandleStandardArgs`.

FindPatch
---------
.. versionadded:: 3.10
The module defines the following variables:
``Patch_EXECUTABLE``
Path to patch command-line executable.
``Patch_FOUND``
True if the patch command-line executable was found.
The following :prop_tgt:`IMPORTED` targets are also defined:
``Patch::patch``
The command-line executable.
.. versionchanged:: 4.0
Imported target is defined only when :prop_gbl:`CMAKE_ROLE` is ``PROJECT``.
Example usage:
.. code-block:: cmake
find_package(Patch)
if(Patch_FOUND)
message("Patch found: ${Patch_EXECUTABLE}")
endif()
