ff210e1c2d arch/stack_color: correct the end address of stack color 
The different optimization of compilers will cause ambiguity in
obtaining sp through up_getsp() in arm_stack_color(), if compile
with clang and enable the optimization flag (-Ofast), up_getsp()
call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.

Compile line:
clang --target=arm-none-eabi -c "-Ofast" -fno-builtin -march=armv8.1-m.main+mve.fp+fp.dp \
-mtune=cortex-m55 -mthumb -mfpu=fpv5-d16 -mfloat-abi=hard -D__NuttX__ -common/arm_checkstack.c -o  arm_checkstack.o

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.
