Enable this option to optimization the unused input sections with the
linker by compiling with " -ffunction-sections -fdata-sections ", and
linking with " --gc-sections ".

This is first script that init runs is rc.sysinit. This
script does serval initialization tasks about basic service.
The boot sequence currently provided to the board level is:
board_earlyinitialize->
board_lateinitialize(Peripherals driver, core driver, ...)->
run rcS script(mount fs, run service) ->
board_appinitialize->
After this patch:
The boot sequence currently provided to the board level is:
board_earlyinitialize->
board_lateinitialize(core driver,...)->
run rc.sysinit script(mount fs, run core service) ->
board_appinitialize(Peripherals driver)->
run rcS script(run other service)->
So, Peripheral drivers can do more with the file system and
core services.

- Add config "ARCH_USE_S_MODE" which controls whether the kernel
runs in M-mode or S-mode
- Add more MSTATUS and most of the SSTATUS register definitions
- Add more MIP flags for interrupt delegation
- Add handling of interrupts from S-mode
- Add handling of FPU from S-mode
- Add new context handling functions that are not dependent on the trap
handlers / ecall
NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
thus S-mode is not usable as is, yet.
## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
