Some services require the ability to query whether a GPIO pin
is configured as an input, output, both, or neither prior to
performing any operations at the service level. This is done
in order to reduce state tracking within the service.
To that end, this change adds
* `gpio_port_get_direction()`
* `gpio_pin_is_input()`, and
* `gpio_pin_is_output()`

Retrieve the pmpaddr value matching the last global PMP slot and add it
to the per-thread m-mode and u-mode entry array. Even if that value is
not written out again on thread context switch, that value can still be
used by set_pmp_entry() to attempt a single-slot TOR mapping with it.
Nicely abstract this with the new z_riscv_pmp_thread_init() where the
PMP_M_MODE(thread) and PMP_U_MODE(thread) argument generators can be
used.

Adds compatibility with Intel ADSP GDB from Zephyr SDK and
from Cadence toolchain to coredump_gdbserver.py.
Adds CAVS 15-25 (APL) register definitions. Implements
handle_register_single_read_packet to serve ADSP GDB
p packets.
Prevents BSA from changing between stack dump printout
and coredump by taking lock. Observed to be necessary for
accurate results on slower simulated platforms.

Triggers CPU exception with illegal instruction when z_except_reason
is called (e.g. in k_panic, k_oops). Creates exception stack frame
for use by coredump. Adds unique cause code for ARCH_EXCEPT. Disables
test case failure for qemu_xtensa.
Without an ARCH_EXCEPT implementation, z_except_reason calls
z_fatal_error directly with a null ESF and bypasses
xtensa_excint1_c's error logging. An ESF is required to coredump.

A QEMU bug may create bad transient PMP representations causing
false access faults to be reported. Work around it by setting
pmp registers to zero from the update start point to the end
before updating them with new values.
The QEMU fix is here with more details about this bug:

This reverts the bulk of commit c8bfc2afda ("riscv: make
arch_is_user_context() SMP compatible") and replaces it with a flag
stored in the thread local storage (TLS) area, therefore making TLS
mandatory for userspace support on RISC-V.
This has many advantages:
- The tp (x4) register is already dedicated by the standard for this
purpose, making TLS support almost free.
- This is very efficient, requiring only a single instruction to clear
and 2 instructions to set.
- This makes the SMP case much more efficient. No need for funky
exception code any longer.
- SMP and non-SMP now use the same implementation making maintenance
easier.
- The is_user_mode variable no longer requires a dedicated PMP mapping
and therefore freeing one PMP slot for other purposes.

The tp (x4) register is neither caller nor callee saved according to
the RISC-V standard calling convention. It only has to be set on thread
context switching and is otherwise read-only.
To protect the kernel against a possible rogue user thread, the tp is
also re-set on exception entry from u-mode.

This commit fixes issue with undefined value during position calculations.
Shift for positions may be >32, so we need to explicitly use unsigned long
casting to prevent unexpected behavior during event handling.

This commit fixes barrier usage in Xen event channel driver. Previously
compiler_barrier() was used and it did not prevent processor from
re-ordering of the write operations, that is needed for correct event
handling. It is now changed to data memory barrier (dmb()), which will
work as expected in this situation.
