[BREAKING] Remove build execution (#740)

Build execution is moved to ui5-project (see SAP/ui5-project#457).
Going forward, ui5-builder shall only provide task implementations and selected helper
modules like TaskUtil.

TaskUtil will provide a new `getProject()` function to custom tasks defining specVersion 2.7 and above.

BREAKING CHANGE:
* builder.js has been removed. Use ui5-project builder instead
* Tasks now rely on Project instances being available on Resources (see SAP/ui5-fs#381)
* TaskRepository#addTask has been removed. Custom tasks need to be added to the project graph instead
* TaskUtil#get/set/clearTag now requires a Project instance to be provided. Path strings are no longer sufficient
  and will cause an exception to be thrown
