The feature depends on ARCH_USE_SEPARATED_SECTION
the different memory area has different access speed and cache
capability, so the arch can custom allocate them based on
section names to achieve performance optimization

1. Similar to asan, supports single byte out of bounds detection
2. Fix the script to address the issue of not supporting the big end

Revert "Parallelize depend file generation"
This reverts commit d5b6ec450f.
parallel depend ddc does not significantly speed up compilation,
intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly

When in a multi-core structure, as the intermediate core,
remote is both the master and slave;When the remote exception or
restart occurs, it needs to notify the slave and reestablish the connection

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.

reason:
In SMP, when a context switch occurs, restore_critical_section is executed.
To reduce the time taken for context switching, we directly pass the required
parameters to restore_critical_section instead of acquiring them repeatedly.
