Move caches to stub files to get around gcc 10 Seems that using the __atribute__ magic for sections is not the best way of doing this, since it injects some default atributtes that collide with the user defined ones. Using assembly is far easier in this case. Reworked definitions a bit to make it easier to import from assembly. Also wrapped stuff around macros for easy and less verbose implementation of the symbol prefix issue.

#ifndef GPSP_CONFIG_H
#define GPSP_CONFIG_H
Add overridable memory config knob for low-mem platforms

/* Default ROM buffer size in megabytes (this is a maximum value!) */
#ifndef ROM_BUFFER_SIZE
Rewrite ROM buffer allocation This improves the existing on-demand ROM paging and also breaks down ROM buffers into 1MB blocks for platforms with memory fragmentation issues. Fixed some potential RTC reg issue in said platforms too. Fixed page pinning on interpreter (would crash due to LRU evictions).

#if defined(SMALL_TRANSLATION_CACHE)
Rework ram block ptrs to remove second indirection table. This removes ram_block_ptrs and encodes the pointer directly in the block tag. Saves ~256KB at no performance cost. Drawback is that it limits the ram cache size to 512KB (we were using 768KB before). Should not be a problem since most games use less than 32KB of cache anyway. Fixed ARM routines accordingly.
