Delete TypeDefault.h and TypeDerived.h codegen entirely. (#47002)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/47002
There was no good reason for TypeDerived.h (CPUType.h) codegen
to exist after static dispatch was deleted, and now that we
have Math alias key TypeDefault.h header is not needed either.
Sorry to anyone who was using these out of tree.
I didn't entirely delete TypeDefault.h as it has a use in
a file that I can't conveniently compile test locally. Will
kill it entirely in a follow up.
