Various Updates and Performance Improvements

This release includes:

• Bump modloader (v1.2.0+) with multi-user support
• Fix boxed value type return leakage, from il2cpp's runtime_invoke calling invoker methods that always box but never free
• Add Logger::Backtrace(uint16_t) and LoggerContextObject::Backtrace(uint16_t) to print backtraces supported by ndk-stack
• Avoid allocations in RunMethod calls, use stack std::array types instead
• Use method pointer invokes for RunMethodThrow, large performance improvement, potential risks of safety when invoking
