his PR cleans up segment related code in main.c.
Also cleans up the linker a bit.
Add memory pool to linker as .bss to validate that it exists properly.
Move framebuffers, gfx, and audio buffers out of racing segment and make its own segment.
Rename framebuffers.c to buffers.c as it contains more than just framebuffers.
Import asserts from sm64 to validate that code segments are not overlapping
Rename segNoload to segmentNoload
Rename 802BA370 segment to trigTables
Rename gMenuSelectionFromEndingSequence to gGotoMenu
Rename gMenuSelectionFromQuit to gGotoMode
Rename SEG_ENDING_SEQUENCES to SEG_ENDING
Rename data_821D10 to ceremonyData
Rename data_825800 to startupLogo
