Andy Ross 0dd83b8c2e kernel: Add k_heap synchronized memory allocator
This adds a k_heap data structure, a synchronized wrapper around a
sys_heap memory allocator.  As of this patch, it is an alternative
implementation to k_mem_pool() with somewhat better efficiency and
performance and more conventional (and convenient) behavior.

Note that commit involves some header motion to break dependencies.
The declaration for struct k_spinlock moves to kernel_structs.h, and a
bunch of includes were trimmed.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
