[Net] Add a priority parameter to URLRequest's constructor

This is so that it is clearer what the intended initial priority of
a URLRequest is.

It is also needed so that we can later enforce that if a URLRequest
is set to ignore limits, it has MAXIMUM_PRIORITY; otherwise, we'd have
to mandate that SetPriority() is called before set_load_flags(), which
is fiddly.

Also standardize on a single URLRequest constructor.
