GCC generates LDADDL instructions when using __atomic_fetch_add() on
aarch64. Explicitly use STADDL to implement odp_atomic_add_rel_u64() and
odp_atomic_sub_rel_u64() functions for better performance.

By default, GCC generates the LDADD/LDADDL instruction for atomic
add/sub/inc/dec functions. These functions could also be implemented on
ARMv8.1 ISA (and above) with the store version, STADD/STADDL instruction
which result in better performance for fastpath applications.

Refactor CPU ABI and implementation files to follow common project inlining
style. odp_cpu_pause() function is now defined only once per architecture.
After this clean-up it's simpler for an implementation to add inlined
versions of CPU module functions.

Add new implementation for the 128-bit atomic operations using GCC builtin
atomics. This improves performance considerably compared to the basic

Moved cpu cycle and pause functions into
arch/x86/odp_arch_cpu_inlines.h.
Uncommented pause function in spec file and removed it
from ABI file. It's safer for ABI compat mode to not have
code included into ABI spec files.
Other architectures use the default odp_arch_cpu_inlines.h,
which does not change the current implementation.

arch is defined as an architecture flag so that optimisations or
necessary differences can be accommodated. When we are unable to
determine the architecture it is incorrect to assign it the value of an
operating system. Instead lets label it correctly as a default and add
an error to the user when an unknown arch is encountered.
