OvmfPkg: move VirtioBlkDxe/Virtio.h to Include/IndustryStandard/Virtio.h

This commit consists of:
- a verbatim move ("similarity index 100%" in git parlance),
- an updated #include directive in VirtioBlkDxe/VirtioBlk.h,
- and an OvmfPkg.dec package entry in VirtioBlkDxe/VirtioBlk.inf, so that
  the new include directory is searched.

-// wraparound is a correct wraparound modulo QueueSize too (it doesn't offset
