ExternalProject: Add option subsection anchors for accessibility from TOC
Use RST subsections for each major step of ExternalProject_Add() This makes finding options easier with less scrolling. For example, finding important Download vs. Test options etc.
Perhaps different RST "*******" may be desired, this was just an idea of how to make sections visible in the table of contents.
Fixes #25129 (closed)
