Split the dirconfig parser into a pure line classifier

The old parser walked a temp buffer with point and pcase'd on
char-after, mixing IO, prefix dispatch, and bucket bookkeeping into
one function. Pull the dispatch out into projectile--dirconfig-classify-line,
which takes a string and returns a (BUCKET . VALUE) tag. The pure
function is unit-testable without buffer plumbing, the IO wrapper
shrinks to a one-shot read + dispatch, and the awkward
(pcase ((pred (lambda ...)) ...)) for the comment-prefix check
becomes a straightforward cond.

No behavior change.
