ui: capture push location on path instances

Currently, we treat "default" and "default-push" as separate paths,
even though they are the same logical entity but with different paths
for different operations. Because they are the same entity and
because we will eventually be implementing an official mechanism
for declaring push URLs for paths, we establish a "pushloc" attribute
on path instances. We populate this attribute on the "default" path
with the "default-push" value, if present. This will enable
consumers stop referencing "default-push" which will make their code
simpler.

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