match: delete unused root and cwd arguments to constructors (API)
Most matchers no longer need the root and cwd
arguments. patternmatcher and includematcher still need the root
argument for subincludes.

# extension to emulate invoking 'dirstate.write()' at the time
# specified by '[fakedirstatewritetime] fakenow', only when
# 'dirstate.write()' is invoked via functions below:
#
# - 'workingctx._poststatusfixup()' (= 'repo.status()')
# - 'committablectx.markcommitted()'
