tests/make: test more details of the :U and :D modifiers

tests/make: replace 'variable expression' with 'expression'

Each expression is based on a variable, there's no need for the
verbosity.  The wording in make's diagnostics will be changed in a
follow-up commit.

tests/make: demonstrate bug in parsing of modifier parts

In the modifier ':S,from,to,', parsing the two parts 'from' and 'to' of
the modifier differs depending on whether the expression is actually
evaluated or merely parsed.  This not only applies to the ':S' modifier,
but also to ':C', ':@var@body@', ':!cmd!', ':[...]', ':?:', '::=' and
':from=to'.

make(1): update and add comments in tests

As a result of the new comments, some line numbers have changed in the
output of the tests.  No other changes.

make(1): indent directives like .info, .if, .for consistently

Done by "pkglint -F *.mk", no manual corrections.

make(1): add tests for combining the :D and :U variable modifiers

make(1): add tests for the :D and :U modifiers

This prepares a refactoring for ApplyModifier_Defined.

make(1): add test for :U modifier

make(1): describe the purpose of each newly added unit test dummy

make(1): add dummies for fine-grained tests, one per single feature

The test names have been derived from the current manual page.

All these tests are dummies right now, and the code from the existing
tests will be moved into the new tests step by step.

This is done to prevent modmisc, escape, varmod-edge and varmisc from
growing without any bounds, and to reduce the side-effects of one test
to the others.
