#5874 Remove all uses of markup macro from scm/*.scm

[David Kastrup]

Remove all uses of markup macro from scm/*.scm

The markup macro is a major portability headache for getting
byte-compilation with Guilev2 to work. This removes all uses of it
from within the scm code base of LilyPond while keeping it around (for
now) for use from files in LilyPond syntax.

This actually also includes the single commit from

Issue 5873: Refactor \markup \pattern
