charport: ALTREP String Interoperability

Provides infrastructure for interoperable ALTREP character vectors. Producers of ALTREP string classes can register access methods, allowing consumers to read supported character vectors through a common interface without materializing them as ordinary R strings. Also provides 'charvec', a reference ALTREP string implementation backed by stable memory slices, with support for efficient and multithreaded construction.
