[PATCH v2] eal: abstract compiler atomics

[Tyler Retzlaff <roretzla@linux.microsoft.com>]

Introduce an abstraction for compiler specific atomics and a meson
option to allow standard C11 atomics use.

Note, this series does not attempt to convert to the use of the
abstraction it only introduces it as per the plan discussed here.

devtools checkatches warnings are expected as we intend no
functional change with this series. Subsequent series will address
the use of __sync_xxx builtins warning.

v2:
  * remove non-explicit rte_atomic_xxx macros.
