QbsProjectManager: Switch to an out-of-process approach

That is, do not link to the qbscore library anymore. Instead, use the
JSON-based API.
Advantages:
    - We can build Qt Creator with qbs support without qbs being present
      on the build machine.
    - Smaller memory footprint for Qt Creator, as the qbs build graphs
      are now being managed by a separate process.
    - Potential crashes in qbs will not kill the Qt Creator process.
