Something like SetGlobalCreateFromNameDelegate?  Particularly keen to get Set in
there so it's clear There Can Be Only One, and Global to remind us it's, well,
global.

Alternatively, if we want to make this a little more backdoor-y, less public, we
could just drop this function entirely, make the function pointer a non-static
global, and have DM declare and set it manually?

Renamed as recommended. I have no opinion about whether to make it more
back-door.

We often have a typedef (and end it with Proc) to make things a bit shorter so
maybe have a

using NameDelegateProc = SkTypeface* (*)(const char name[], SkTypeface::Style
style);

We're already using this type in three places, so it would be nice to have a
name so we're not repeating.

Done.
