ExternalProject: Refactor pre-configure steps to support no-target uses

The mkdir, download, update and patch steps are used by FetchContent during the configure phase of the main build. Because these steps need a target, this has so far required a sub-build to be set up. The changes here factor out the preparation of the scripts from the creation of the targets, allowing future work to leverage these steps without a sub-build (see #21703). As part of the refactoring, some rationalisation of the stamp files, repository info files and script names was done to make things more consistent between download methods and step implementations. Every download method now records its own specific repository info in a file and that file is a dependency of the download step. The source directory is also written to that file, so if the SOURCE_DIR changes, the download will be retriggered (the existing implementation fails in this scenario). Each download method now also has just one driver script that implements the whole step (it may pull in other scripts to do its task though). The patch step gained support for USES_TERMINAL as a result of generalising the implementation for custom commands. Fixes: #21748

+fetchcontent-performance
+------------------------
+
+* The implementation of the :module:`ExternalProject` module was
+  significantly refactored.  The patch step gained support for
+  using the terminal with a new ``USES_TERMINAL_PATCH`` keyword
+  as a by-product of that work.
