Update portal-related memory context names and API

Browse Source 
Rename PortalMemory to TopPortalContext, to avoid confusion with
PortalContext and align naming with similar top-level memory contexts.

Rename PortalData's "heap" field to portalContext.  The "heap" naming
seems quite antiquated and confusing.  Also get rid of the
PortalGetHeapMemory() macro and access the field directly, which we do
for other portal fields, so this abstraction doesn't buy anything.
