This commit does the following.
- Renames `slashslash` as `dumbComments`. As a result, it now comes before
`emptyLines` in alphabetical ordering, which means that if you apply both
`dumbComments` and `emptyLines`, lines that contain only comments will be
fully removed.
(I contemplated changing the filter ordering to match the order specified,
rather than using alphabetical ordering, but that was more invasive and not
obviously better.)
- Changes `dumbComments` so it only applies if the comment is at the start of
the line (with optional leading whitespace). This is so it can be used with
prefs files, which contain lines like `pref("foo", "https://mozilla.org");`
where the `//` must not be treated as a comment.
Note that `slashslash` wasn't being used anywhere.

It's not used, probably because it's pretty strange and hard to imagine using
safely. (Stripping leading and trailing space could be useful, but collapsing
sequences of spaces? Hmm.)

As shown by python/mozbuild/mozbuild/test/test_preprocessor.py, whitespace is
allowed within expressions, and chained #if/#elif/#else sequences work as you'd
expect.
