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

Assembler code:
llvm-objdump -aS arm_checkstack.o

8defb843aa Remove duplicate linker script definitions
## 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
