DisplayCutout: Fix attrs.xml javadoc
Fixes an issue with the javadoc for windowLayoutInDisplayCutoutMode.
Removes @tags from enum javadocs, because they get merged into a table,
which does not support inner @tags. Instead, use <code> tags which work
in that context.
Also replaces @see tags with {@link} tags in the attr javadoc, because
the enum value table gets appended, but it is invalid to have text after
an @see tag.
