a4e93be0fb arch:xtensa: fix sp duplicate reduce in handler enter
In xtensa/include/irq.h the XCPTCONTEXT_SIZE is
`#define XCPTCONTEXT_SIZE    ((4 * XCPTCONTEXT_REGS) + 0x20)`

XCPTCONTEXT_SIZE is already byte size of xcpcontext

fbc1da98b7 xtensa: use swint to swith context
Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.

7b00c8bdb8 arch:xtensa: modify svcall to swint
Reason: xtensa svcall only have level-1 interrupt level.
Sush do not generate interrupt when up_irq_save.
Software int can generate interrupt when up_irq_save.

fb43fd73ed signal: signal handler may cause task's state error
For example, task is blocked by nxsem_wait(sem1), use nxsem_wait(sem2)
in signal handler, and take sem2 successfully, after exit from signal
handler to task, nxsem_wait(sem1) returns OK, but the correct result
should be -EINTR.

d2bc011719 arch/xtensa/xtensa_cpupause.c: Allow a spin before taking the g_cpu_wait
spinlock.

If we repeatedly call up_cpu_pause and up_cpu_resume, there would be
cases where the next call to up_cpu_pause happens while the other CPU is
still responding to the previous resume request.  In this case the
DEBUGASSERT will trigger.  We should allow the first CPU to wait until the
other CPU has finished responding to the resume request.
