7b9978883c arch/arm: optimize context switch speed
The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

SP overlap in SVC and USR mode

This commit change the default CPU mode to System and ensure the consistency of SP/LR in USR/SYS mode during syscall.

625d230d28 arch/arm/src/stm32f7/stm32_can.c: fix CAN3 receiving
by fixing filter initialization.

STM32F7 CAN3 works in single peripheral configuration and there is only 14 filter banks: 0-13. Previously not available 14 indexed filter (CAN_NFILTERS/2) was wrongly used for for receiving to FIFO. Now zero indexed filter is correctly used instead.

## 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!
