Support hardware debugging of ARM architecture, and support smp mode.We can use "up_debugpoint_add" or "up_debugpoint_remove" to add breakpoints, and the hardware will jump into the interrupt after detecting it.

test:
1.use mps3-an547 build helloxx as module and run it
2.use qemu-armv7a:knsh test kernel build helloxx and run it

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

Purpose: make the the os crash when busyloop with interrupt disable
Follow the arm gicv2 spec, if we want to use the IRQ and FIQ
simultaneously when not using the processor Security Externsions.
We should:
1. IRQ to Group 1 and FIQ to Group 0;
2. Set CICC_CTLR.FIQEn to 1;
Then in NuttX:
1. implement the arm_decodefiq and directly crash in it;
2. provide interface to change the IRQ to FIQ, e.g. change the
watchdog IRQ to FIQ, so the watchdog can trigger even with the
interrupt disabled (up_irq_save() called);

Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.

The dependency should be vice versa; the MM_SHM should depend on the
existence of the virtual memory range allocator.
Create a new CONFIG flag CONFIG_ARCH_VMA_MAPPING, which will define that
there is a virtual memory range allocator. Make MM_SHM select that flag

Adds stubs for up_addrenv_text_enable/disable_write. These don't have
to do anything as the ARM MMU allows setting access per mode. Currently
the settings for user .text area grants the kernel write access, but
revokes user write access.
