1e49cb4828 armv7-a/armv7-r/armv8-r: percpu reg store this_task
This is continue work of https://github.com/apache/nuttx/pull/13726

We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.

up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.

up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.

610efc8f1a arm: remove up_set_current_regs/up_current_regs
reason:
up_set_current_regs initially had two functions:

1: To mark the entry into an interrupt state.
2: To record the context before an interrupt/exception. If we switch to
   a new task, we need to store the upcoming context regs by calling up_set_current_regs(regs).

Currently, we record the context in other ways, so the second function is obsolete.
Therefore, we need to rename up_set_current_regs to better reflect its actual meaning,
which is solely to mark an interrupt.

6036a318f4 compiler: add __ARM_ARCH, __ARM_FEATURE_DSP macro definition in ghs
when we build mbedtls in vela with ghs compiler, the mbedtls need to
access __ARM_ARCH and __ARM_FEATURE_DSP, and to construct the inline asm
code based on these two macros.
With ghs compiler, these two macros are not defined, and will be
evaluated as 0 by default, and thus will using to wrong inline asm code,
in order to handle this issue, we need to add conversion between the ghs
and gcc with __ARM_ARCH, __ARM_FEATURE_DSP

The current context save implementation saves registers of each task

already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
