Andrew Boie 7c43992f22 profiler: use new ring buffer data structure
The profiler now uses the generic ring buffer. The dropped event
count is stored in the ring buffer's value field. The data size only
refers to the extra data attached to the message and NOT any internal
representation of metadata inside the ring buffer, the event_logger
APIs now pass this information along in dedicated parameters.

Yonattan Louise 5c6ef8fdb5 Profile low condition events.
Add the sleep events point for x86 and ARM arquitectures that gives
information about when the CPU went to sleep mode, when it woke up
and which interrupt causes the CPU to awake.

Yonattan Louise d2108bf084 Profile interrupt events.
Add the interrupt profile points for x86 and ARM arquitectures. This
gives information regarding the time when interrupts occur.

Benjamin Walsh 0dcad8331b clarify use of term 'context'
The term 'context' is vague and overloaded. Its usage for 'an execution
context' is now referred as such, in both comments and some APIs' names.
When the execution context can only be a fiber or a task (i.e. not an
ISR), it is referred to as a 'thread', again in comments and everywhere
in the code.

APIs that had their names changed:

  - nano_context_id_t is now nano_thread_id_t
  - context_self_get() is now sys_thread_self_get()
  - context_type_get() is now sys_execution_context_type_get()
  - context_custom_data_set/get() are now
    sys_thread_custom_data_set/get()

The 'context' prefix namespace does not have to be reserved by the
kernel anymore.

The Context Control Structure (CCS) data structure is now the Thread
Control Structure (TCS):

  - struct ccs is now struct tcs
  - tCCS is now tTCS

Yonattan Louise efd8e246cc Add profiler method.
Add a standardized mechanism to add profiling points to the Kernel
with a single interface for the user to collect the profiling data.
