SkipInstallOperation placeholders

For some devices, some InstallOperations can be skipped during the
update process.  An example is the SOURCE_COPY operation with same
source and destination locations for Virtual A/B devices.
This patch extents the DynamicPartitionControl interface with the
ShouldSkipOperation() method to query if given operation should be
skipped or not.
