Stop passing der::Input by const-ref

Span/view types are small enough that the guidance these days is to pass
by value. This CL is the result of two sed lines:

  sed -i -e 's/const Input &/Input /g' pki/*.*
  sed -i -e 's/const der::Input &/der::Input /g' pki/*.*

Plus one manual fix inside a comment in pki/parser.h where the spacing
didn't match. Then a clang-format -i
