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.

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

+	  You can use any image format supported by imagemagick, a list of which
+	  can be found [here](https://imagemagick.org/script/formats.php).
+
+	  The build process will automatically convert this to the format that
+	  edk2 requires, which is an uncompressed BMP, in BMP3 format. It does
+	  this using imagemagick (`convert splosh.bmp BMP3:splash.bmp`).
+
+	  The newly formatted file will be the dimensions size as the original
+	  one.
+
+	  The build process will automatically do this conversion, so it can
+	  be supplied with any format that imagemagick can process (which is
+	  pretty much any!).
+
+	  This image will also be used as the BGRT boot image, which may
+	  persist through your OS boot process.
+
+	  See ACPI spec 6.3, 5.2.22 Boot Graphics Resource Table (BGRT), and
+	  Microsoft's documentation on BGRT positioning:
+	  Docs/Windows/Windows Drivers/Bring up guide/Boot screen components
+
+	  Accordingly, the image used should be no taller/wider than 40% of
