Support additional ops for Quote transformations.

[raulraja]

Currently, quote transformations are limited to Transform.replace which replaces a returned node by a list of declarations. There is an additional set of operations that we would like transformation to be used on.

We would like to support further transformations:

Transform	Description
replace	Replaces selected node by list of new declarations
remove	Removes one or n nodes
relocate	Places this node elsewhere in the tree
newSources	wraps other transforms and outputs their result in other KtFiles
diagnose	Returns a list of Diagnostic that the compiler should present to the user
many	wraps a list of transforms and when interpreted executes them in order
+	many(this, other)
empty	noop
debug	wraps a transform and enables tracing thru its a progression over the internals

We should do one PR per transform and ensure these transformations are tested with the quoteOutputMatchescombinators in the testing library. The testing library would need to receive a few additional algebras to verify produced sources in the newSources transform
