This set of functions seem to be there just because of historical
reasons, stemming from Kbuild. They are non-obvious and prone to errors,
so remove them in favor of the `_ifdef()` ones with an explicit
`CONFIG_` condition.

When `CONFIG_UART_ASYNC_API` is enabled, cleanup any pending synchronous
receptions at initialization time. Pending receptions are present when
this driver is used with the default mcuboot application.
When `CONFIG_UART_ASYNC_API` is not enabled, RX is always enabled by
this driver. As mcuboot does not use the async API, and does not cleanup
the UART driver before jumping to the next application, that application
boots with RX still enabled. This results in a 500uA increase in current
consumption.

There are predictable relationships between the actual size
of a stack object, the return value of K_*_STACK_SIZEOF() macros,
and the original size passed in when the stack was declared.
Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
These stacks are appropriate for threads that run purely in
supervisor mode, and also as stacks for interrupt and exception
handling.
Two new arch defines are introduced:
- ARCH_KERNEL_STACK_GUARD_SIZE
- ARCH_KERNEL_STACK_OBJ_ALIGN
New public declaration macros:
- K_KERNEL_STACK_RESERVED
- K_KERNEL_STACK_EXTERN
- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF
If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.
Separately generated privilege elevation stacks are now declared
like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN.

The core kernel computes the initial stack pointer
for a thread, properly aligning it and subtracting out
any random offsets or thread-local storage areas.
arch_new_thread() no longer needs to make any calculations,
an initial stack frame may be placed at the bounds of
the new 'stack_ptr' parameter passed in. This parameter
replaces 'stack_size'.
thread->stack_info is now set before arch_new_thread()
is invoked, z_new_thread_init() has been removed.
The values populated may need to be adjusted on arches
which carve-out MPU guard space from the actual stack
buffer.
thread->stack_info now has a new member 'delta' which
indicates any offset applied for TLS or random offset.
It's used so the calculations don't need to be repeated
if the thread later drops to user mode.
CONFIG_INIT_STACKS logic is now performed inside
z_setup_new_thread(), before arch_new_thread() is called.
thread->stack_info is now defined as the canonical
user-accessible area within the stack object, including
random offsets and TLS. It will never include any
carved-out memory for MPU guards and must be updated at
runtime if guards are removed.
Available stack space is now optimized. Some arches may
need to significantly round up the buffer size to account
for page-level granularity or MPU power-of-two requirements.
This space is now accounted for and used by virtue of
the Z_THREAD_STACK_SIZE_ADJUST() call in z_setup_new_thread.

A new macro Z_THREAD_STACK_OBJ_ALIGN() defines the alignment
of the lowest memory address of a stack object.
Related is a new arch interface ARCH_THREAD_STACK_OBJ_ALIGN()
which lets arches specifiy this. ARCH_STACK_PTR_ALIGN or a
power-of-two ceiling is used if not defined.
The default stack macros now use this instead of hard-coding
ARCH_STACK_PTR_ALIGN.
