[MAT-387] Use shared_ptr for registers

Instead of using the PtrContainer<const OGNumeric*>, we now use
an std::vector<std::shared_ptr<OGNumeric*>> for the registers.

[MAT-387] WIP broken

[MAT-387] Use shared_ptr for ArgContainers

A large knock-on effect results from this change. The PtrVectors
are largely redundant so they are removed.

Changed to the dispatching to real16/complex16 AoAs were also
required to simplify things.

[MAT-387] Remove accidental double shared_ptr wrapping

[MAT-387] Correct segfault in pinvrunner

[MAT-387] Fix segfault in jdispatch test

[MAT-387] Some shared pointer changes, librdag builds but is not linkable.

[MAT-387] Fixed linkage, but still no compilation

[MAT-387] Part conversion of equals test

[MAT-387] check_equals compiles, and does not segfault

[MAT-387] Lazily set _fuzzyref because we don't have a shared_ptr to pass to its constructor at the construction time of an OGTerminal

[MAT-387] More explicit comparison
