Subject: renderer_opengl/gl_global_cache: Append missing override specifiers

Two of the functions here are overridden functions, so we can append
these specifiers to make it explicit.

Subject: renderer_opengl/gl_global_cache: Replace indexing for assignment with
 insert_or_assign

The previous code had some minor issues with it, really not a big deal,
but amending it is basically 'free', so I figured, "why not?".

With the standard container maps, when:

map[key] = thing;

is done, this can cause potentially undesirable behavior in certain
scenarios. In particular, if there's no value associated with the key,
then the map constructs a default initialized instance of the value
type.

In this case, since it's a std::shared_ptr (as a type alias) that is
the value type, this will construct a std::shared_pointer, and then
assign over it (with objects that are quite large, or actively heap
allocate this can be extremely undesirable).

We also make the function take the region by value, as we can avoid a
copy (and by extension with std::shared_ptr, a copy causes an atomic
reference count increment), in certain scenarios when ownership isn't a
concern (i.e. when ReserveGlobalRegion is called with an rvalue
reference, then no copy at all occurs). So, it's more-or-less a "free"
gain without many downsides.
