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

The link script of NuttX Simulator is generated through compilation
options. This PR will support configure special data sections in
kconfig to meet the support of 3rd party applications.
we need to follow the syntax of linker script. In 3rd-party applications, some data will be labeled as section:
| a.c:
| struct task_s a __attribute__((section(".data.custom.taska")));
| b.c:
| struct task_s b __attribute__((section(".data.custom.taskb")));
Data of the same type struct can be placed in a fixed location to reduce the overhead caused by searching:
| .data :
| {
| _custom_data_table_start = .;
| KEEP(*(.data.custom.*))
| _custom_data_table_end = .;
| }
Such section declare can be configured via Kconfig in the PR:
| CONFIG_SIM_CUSTOM_DATA_SECTION=" .data : { _custom_data_table_start = .; KEEP(*(.data.custom.*)) _custom_data_table_end = .; } "

Note: This implementation is a bit more relaxed than what we do for
non-cmake builds. Mainly because I'm not familiar enough with cmake
to mirror what the non-cmake version does.
hostfs has its copies of some of nuttx definitions with different
names to avoid conflicting with the host OS definitions.
sometimes people only modifies one of them and forgets updating
another. eg. https://github.com/apache/nuttx/pull/11445
this commit introduces some assertions to detect that kind of
mistakes.
