Struct reading and disassembly script overhaul, various misc. loading fixes, bump to .NET 9 (#13)

* Bump projects to .net 9 and update nugets

* add VersionedSerialization + source generator

* migrate versioning to StructVersion class, add handling/detection for 29.2/31.2

* add new struct definitions

* rename serialization methods and add BinaryObjectStreamReader for interop

* Rework metadata struct loading to use new struct versioning

* move 29/31.1/.2 to use tags (-2022,-2023) instead of minor versions

* fix metadata usage validity checks

* rework code registration offsetting a bit and add second 29/31.1 condition

* tweak .1 condition (again)

* 29/31.2 was a psyop

* also remove 29.2 from the readme

* remove loading of packed dlls - this was a very unsafe feature

* support auto-recovering type indices from type handles
fixes loading of memory-dumped v29+ libraries since those replacee their class indices on load with a pointer to the corresponding type

* support loading PEs without an export table

* also read UnresolvedVirtualCallCount on regular v31

* Disable plugin loading for now

* Overhaul disassembler script + add Binary Ninja target (#12)

* Overhaul diassembler scripts:
- No longer defines top level functions
- Split into three classes: StatusHandler (like before), DisassemblerInterface (for interfacing with the used program API), ScriptContext (for definiting general functions that use the disassembler interface)
- Add type annotations to all class methods and remove 2.7 compatibility stuff (Ghidra now supports Python 3 so this is unnecessary anymore)
- Disassembler backends are now responsible for launching metadata/script processing, to better support disassembler differences
- String handling is back in the base ScriptContext class, disassembler interfaces opt into the fake string segment creation and fall back to the old method if it isn't supported

* Add Binary Ninja disassembler script backend
This uses the new backend-controlled execution to launch metadata processing on a background thread to keep the ui responsive

* make binary ninja script use own _BINARYNINJA_ define and add define helpers to header

* Update README to account for new script and binary ninja backend

* implement fake string segment functions for binary ninja but don't advertise support

* also cache API function types in binary ninja backend

* fix ida script and disable folders again

* Fix metadata usage issues caused by it being a value type now

* make TryMapVATR overrideable and implement it for ELFs

* Make field offset reading use TryMapVATR to reduce exceptions

* Fix NRE in Assembly ctor on < v24.2

* Update actions workflow to produce cross-platform CLI binaries, update readme to reflect .net 9 changes

* workflow: only restore packages for projects that are being built

* workflow: tweak caching and fix gui compilation

* workflow: remove double .zip in CLI artifact name

* 29/31.2 don't actually exist, this logic is not needed
