payloads/tianocore: Rename TianoCore to edk2

coreboot uses TianoCore interchangeably with EDK II, and whilst the
meaning is generally clear, it's not the payload it uses. EDK II is
commonly written as edk2.

coreboot builds edk2 directly from the edk2 repository. Whilst it
can build some components from edk2-platforms, the target is still
edk2.

[2] tianocore.org - "EDK II is a modern, feature-rich, cross-platform
firmware development environment for the UEFI and UEFI Platform
Initialization (PI) specifications."
