[sync] Componentize sync: Part 5: Eliminate filename collisions in sync.gyp

In order to move src/sync into its own compoent, all the static_library targets in sync.gyp need to be converted to targets of type 'none' and rolled into one sync target of type component. This is currently blocked by duplicate .cc filenames in syncable and internal_api, which flags an error while running gyp. The offending files are {internal_api|syncable}/{base|read|write}_transaction.cc.

This patch renames syncable/{base|read|write}_transaction.{h|cc} to syncable/syncable_{base|read|write}_transaction.{h|cc}.
