streamclone: teach canperformstreamclone to be bundle2 aware

We add an argument to canperformstreamclone() to return False if a
bundle2 stream clone is available. This will enable the legacy stream
clone step to no-op when a bundle2 stream clone is supported.

The commented code will be made active when bundle2 supports streaming
clone.

This patch does foreshadow the introduction of the "stream" bundle2
capability and its "v1" sub-capability. The bundle2 capability mirrors
the existing "stream" capability and is needed so clients know whether a
server explicitly supports streaming clones over bundle2 (servers up to
this point support bundle2 without streaming clone support).

The sub-capability will denote which data formats and variations are
supported. Currently, the value "v1" denotes the existing streaming
clone data format, which I intend to reuse inside a bundle2 part. My
intent is to eventually introduce alternate data formats that can be
produced and consumed more efficiently. Having a sub-capability means
we don't need to introduce a new top-level bundle2 capability when new
formats are introduced. This doesn't really have any implications
beyond making the capabilities namespace more organized.
