Introduces a model of architectures
that will contain CPU-specific code such as size of pointer or
instruction disassembler. Each `GDBFrame` and `GDBInstruction` now
can answer its architecture. In case the architecture is not
reported by GDB or nknown to 'jv:libgdbs' a generic "unknown"
architecture ir returned.
Note that this feature requires a patch to current GDB [1]. Future
releases of GDB will hopefully have it already integrated.

Sub-instances of GDBArchitecture models a target
architecture such as x86_64, PowerPC or RISC-V and
provides architecture-specific services.
In GDB, each frame has associated architecture (and
may differ from architecture of other frames!!)
