comments: remove "Horror Vacui" rule

The rule about avoiding comments in C code where the opening comment
characters are alone on a line conflicts with everyday edk2 practice --
we use comments like

  //
  // If the total number of lines in the popup is zero, then ASSERT()
  //

all the time. This comment style is actively enforced by reviewers and
maintainers. Remove the rule in order for the CCS to match reality.
