LP1835982 Grid cell text generator API migration

Migrate cell-specific cellPrintValue handlers to a grid-wide
cellTextGenerator handler.  This simplifies the client-side API and
helps to formalize the API a bit more by providing a new
GridCellTextGenerator interface.

Warning messages are now display at page load time when a grid cell uses
a cellTemplate but does not have a matching text generator.
