refactor(xlat): add several refactorizations to the xlat library
This patch includes a number of refactorizations of the xlat library in
order to facilitate the implementation of unittests for the library.
Amongst the improvements there are:
* Macros to allocate and initialize the translation tables as well
as the translation context structures have been removed and
replaced with library APIs.
* Some of the library APIs have been collapsed, reducing the size
of the overall interface and presenting a more compact API to
the consumer.
* The distinction between the translation base tables and the
intermediate tables have been removed, presenting now a single
array of tables for the whole translation context.
The patch also adapts the rest of RMM to use the new library API.
