Michel Heily dc7cd24e8d [perf] Refactor&Optimize inner core::arm7tdmi APIs.
Avoid passing ArmInstruction struct to handlers, as accesses to its fields can result in memory operations.

Michel Heily bf601404fa Optimize cartridge Bus reads
The `if let Some(gpio) = &self.gpio` causes a memory read of `self.gpio` for every Bus::read/write_16.
It is better to reverse the order since `is_gpio_access` does not generate and memory reads and thus less costly.

Michel Heily ba2eff82ac platform/android: Big re-write of native interface
Mainly convert mainloop and audio thread into native code for
performance increase. (Calling into JNI every frame was costy)

The code was cleaned up quite a bit, but I may have introduced new bugs
in this process :<

Michel Heily 90e492d81a core/sysbus: Get rid of memory_map! macro
While saving code re-use, it won't allow flexibility for special casing
specific size bus accesses which are much needed in order to emulate
open-bus and bios reads
