[cmake] refactor: Use CPM over submodules (#143)

Transfers the majority of submodules and large externals to CPM, using source archives rather than full Git clones. Not only does this save massive amounts of clone and configure time, but dependencies are grabbed on-demand rather than being required by default. Additionally, CPM will (generally) automatically search for system dependencies, though certain dependencies have options to control this.

Testing shows gains ranging from 5x to 10x in terms of overall clone/configure time.

-// using_std_string.h: Allows building this code in environments where
-//                     global string (::string) exists.
-//
-// The problem:
-// -------------
-// Let's say you want to build this code in an environment where a global
-// string type is defined (i.e. ::string).  Now, let's suppose that ::string
-// is different that std::string and you'd like to have the option to easily
-// choose between the two string types.  Ideally you'd like to control which
-// string type is chosen by simply #defining an identifier.
-//
-// The solution:
-// -------------
-// #define HAS_GLOBAL_STRING somewhere in a global header file and then
-// globally replace std::string with string.  Then include this header
-// file everywhere where string is used.  If you want to revert back to
-// using std::string, simply remove the #define (HAS_GLOBAL_STRING).
