topology: pre-process-object: Add support for data objects

Pre-process data objects, create the SectionData and update
the parent object with the reference to the object.
For example, the following object instance:

	Object.Base.data."SOF_ABI" {
		bytes	"0x03,0x12,0x01"
	}

would update the SectionManifest as follows:
SectionManifest."sof_manifest" {
	data [
		"SOF_ABI"
	]
}
