WIP: Update CMake min version from 3.17 to 3.23 (TriBITSPub#411)

This is part of allowing TriBITS to take advantage of newer CMake features and replacing some older TriBITS code that now has (better or compatiable) native implementations in CMake (many years later). The min version of CMake 3.23 is chosen due to Trilinos (see trilinos/Trilinos#10355). Some non-obvious changes made were: * For some reason, find_file() wiht CMake 3.23 (and using CMak 3.23 default policies) adds on an extra '/' before the file name. This messed up the test checks but I fixed that by putting in '[/]*' in the regex to account for that. * Updated the GitHub Actions testing jobs to all be CMake 3.23+. (I updated the patch versions as well to the most recent patch releases as of right now. CMake 3.25 is still the most recent release of CMake as CMake 3.26 is still in release candidate testing.) * Add checks for setting CTEST_RESOURCE_SPEC_FILE in CTestTestfile.cmake now that CMake is >= 3.18. * Removed constant ${PROJECT_NAME}_CTEST_USE_NEW_AAO_FEATURES since it is hard-coded since CMake is 3.17+. * Removed some documentation discussing older versions of CMakew (which are no longer supported). * install-cmake.py: Changed the default version of CMake to install from 3.17 to 3.23. * install-cmake.py: Removed patch for CMake 3.17 * Removed documentation for Kitware fork of Ninja version < 1.10 since Ninja 1.10 has been out for many years.

 ChangeLog for TriBITS
 ----------------------------------------
 
+## 2023-02-24:
+
+* **Changed:** Upgrade minimum required CMake version from 3.17 to 3.23.
+  Existing TriBITS projects that have already upgraded to require CMake 3.23+
+  should not notice any major changes due to this change.
+
 ## 2023-02-21:
 
-* Add support for pre-installed internal packages treated as external
-  packages.  Now, any set of internally defined TriBITS packages for a TriBITS
-  project can be pre-built and pre-installed and the remaining packages in the
-  TriBITS project can be configured to point to those by setting `-D
-  TPL_ENABLE_<Package>=ON`.  This allows great flexibility in how a TriBITS
-  project's packages can be and built, installed, and deployed.  This
-  technically implements "Use Case 3: Configure/build pointing to a subset of
-  already installed TriBITS packages in same repo" in [TriBITS
+* **Added:** Added support for pre-installed internal packages treated as
+  external packages.  Now, any set of internally defined TriBITS packages for
+  a TriBITS project can be pre-built and pre-installed and the remaining
+  packages in the TriBITS project can be configured to point to those by
+  setting `-D TPL_ENABLE_<Package>=ON`.  This allows great flexibility in how
+  a TriBITS project's packages can be and built, installed, and deployed.
+  This technically implements "Use Case 3: Configure/build pointing to a
+  subset of already installed TriBITS packages in same repo" in [TriBITS
   #63](https://github.com/TriBITSPub/TriBITS/issues/63).  See the section
   "Building against pre-installed packages" in the updated build reference
   documentation for details.
