Add a collectToIpc for zero-copy transmission that isn't version-locked to Arrow

[westonpace]

Currently when users grab results they are given two less than ideal options. They can use collectToArrow which will return the results as Arrow objects. This requires a very exact match between the library Arrow version and the caller Arrow version. This is even more difficult than the usual headache (bumping user library requires bumping flight library) because JS can easily duplicate dependencies or code paths in the presence of bundlers. For this reason it is often safest to use collectToObjects. However, collectToObjects is not a zero-copy operation and requires the data to be marshaled into JS.

An alternative, which should give the best of both worlds, is to collect into an IPC stream. The caller can then decode the IPC stream with their Arrow library. This will copy all the metadata but none of the data. This should allow callers to use whatever Arrow version they desire.
