• All of the macros from uefi_macros are imported into the uefi crate. Consistently use those imports everywhere, rather than reimporting fromuefi_macros.
• Consistently import items in theuefi crate withcrate:: instead ofuefi::.
• Clean up unnecessary uses ofself::.

Should be no change to the public API from this.

Checklist

• Sensible git history (for example, squash "typo" or "fix" commits). See theRewriting History guide for help.
• Update the changelog (if necessary)
