The sim_bthcisock_interrupt() handler for Bluetooth HCI sockets in the simulatorwas using
an if statement to check for available data on the HCI socket. Thismeant that only a single
packet would be read and processed per interrupt trigger,even if multiple packets were waiting
in the socket buffer.
This led to incomplete data processing: unread packets would remain in the bufferuntil the next
interrupt tick, causing delayed handling of Bluetooth HCI events/commands,packet backlogs,
or missed data in high-throughput scenarios.
This fix replaces the if with a while loop to:
1. Continuously check for and read available data from the HCI socket until no more
packets are present in the buffer.
2. Ensure all pending HCI packets are processed in a single interrupt handler invocation.
3. Eliminate packet backlogs and reduce latency in Bluetooth HCI communication.
The change maintains the same core data reception logic (bthcisock_receive()) butensures it runs
for all available packets, improving the reliability and responsivenessof the simulator's Bluetooth HCI socket implementation.

Add validation to ensure allocated stack size does not exceed TLS_MAXSTACK when
CONFIG_TLS_ALIGNED is enabled, and verify proper stack alignment using STACK_ALIGN_MASK
across all architectures. This improves stack safety and prevents potential TLS overflow conditions.

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.

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.
