Bluetooth: Controller: Add a util folder with basic primitives The util folder contains memory management, queue management and misc utilities used by the Link Layer implementation. This will be in time replaced by Zephyr's native functionality.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

Bluetooth: Controller: replace work with mayfly This commit introduces a very light-weight and lock-less scheduling of the Controller's deferred function calls called the Mayfly. Earlier work implementation used in the Controller had an O(n) to schedule a function in a linked list that used IRQ lock during modification of the linked list in the Controller's ISR executions. Mayfly is a compile time configurable matrix of queues where an execution context-safe queue exists between two execution context, one being the caller and the second being the callee. Callee(s) are run in a software interrupt but can also be run in an OS thread. There are minor clean ups too in this commit related to folder structure.
