Remove restore_critical_section() call from up_switch_context() in simulator
as it is not necessary during interrupt context switching. The critical
section state is properly managed elsewhere in the interrupt handling flow.

Move stack alignment and kernel stack macros from architecture-specific internal
headers to public include/nuttx/irq.h. Consolidates duplicate definitions across
17 architecture families, reducing code duplication while enabling common code
to access these core alignment utilities without architecture dependencies.

1. Use reserved[0] filed in struct fw_rsc_vdev and the driver
master/slave to judge the device role;
2. Use struct fw_rsc_carveout in resource table to provide the
share memory to virtio driver side;

rpmsg work in hpwork are waiting for remote buffer, remote get buffer and callback, but callback also in hpwork, deadlock occurs here.
now we move periodic work to global work queue instead of hpwork to fix deadlock.

The wdog callbacks are executed in the host's signal handler context, which has strict limitations on what operations can be safely performed. Specifically, signal handlers should not call non-async-signal-safe functions (e.g., sim_alsa use mutex_lock in wdog and cause deadlock).
This change only replaces uses of wdog for periodic tasks. Other interrupt callbacks that are still invoked from the host signal handler are not replace to work queue.

Remove the interception of unknown levels and option names in sim usrsock.
This allows the system socket interface to handle them and return the correct error codes or behavior, rather than returning a generic error locally.

Avoid the errno changed after interrupt in sim and make return value
mistake when according to errno.
Move host_errno_convert from macro to sim_errno.c.

We will remove the API in next commit, so remove the errno manual save
API and save errno more commonly.
After whole pull request, should no longer need to care about errno.

The USB driver framework only implements a single ISOC transfer.
If multiple transfers are needed, the class driver can initiate
multiple urbs to meet the real-time requirements of the ISOC
endpoint. The class driver's urb record the buf address, length,
and number of packets sent. The callback function calculates the
data location in the buf based on the callback number and length
returned.

On success, zero (OK) is returned. On a failure, a negated errno value
is returned indicating the nature of the failure.
