hujun5 6f03601169 arch: rename STACK_ALIGNMENT to STACKFRAME_ALIGN across all architectures 
Rename STACK_ALIGNMENT macro to STACKFRAME_ALIGN throughout the codebase
to provide clearer naming semantics. The new name better reflects the macro's
purpose of frame alignment rather than general stack alignment.

hujun5 8bb250a4c0 arch: move STACK_ALIGNMENT to irq.h 
Move STACK_ALIGNMENT macro definitions from architecture-specific internal
headers to public irq.h headers. This enables common code to directly access
STACK_ALIGNMENT without requiring internal header inclusion, improving code
organization and reducing header dependencies. Applies to all architectures:
ARM, ARM64, AVR, HC, MIPS, or1k, Renesas, RISC-V, SIM, SPARC, TriCore, x86,
x86_64, Xtensa, Z16, and Z80.

cuiziwei f1d180d56e nuttx/sim: Remove math.h in sim. 
The reason for removing math.h is that undefining __GLIBC__ does not take effect. By default, sim will use the toolchain's math library and undef __GLIBC__ in the source file.

hujun5 908df725ad arch: use up_current_regs/up_set_current_regs replace CURRENT_REGS 
reason:
1 On different architectures, we can utilize more optimized strategies
  to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.
