[4/8] examples/performance-thread: rename directory to standard

  In other places in DPDK, e.g. EAL, the architecture-specific files for arm
are just stored in a folder called "arm". Rename the "arm64" folder for
performance thread example to align to this naming.

This code only works for arm64 as it is storing and restoring arm64 registers.
armv7 registers are different so this code does not work for the generic arm.

arm64 specific code, we always named as arm64

F: lib/librte_hash/rte*_arm64.h
F: lib/librte_efd/rte*_arm64.h
F: lib/librte_table/rte*_arm64.h

IMO, If armv7 support adds in future then we can change the directory
as arch/arm
and have ctx_64.c and ctx_32.c etc. I think, for now, technically it
is correct to call the directory as arm64

Ok, fair enough. The code isn't meant to build for ARMv7 so I thought I'd
save some logic by just using x86 and arm, rather than having to compute
the directory names individually.

I'll rework the patch.
