[PATCH] RFC: use C11 alignas instead of GCC attribute aligned

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

Now that we require a C11 conformant toolchain we are able to improve
portability by further adoption of C11 features.

Adapt EAL to use C11 alignas replacing __rte_cache_aligned and
__rte_aligned(a) that expand to __attribute__((__aligned__(a))).

Note: it appears that use of alignas has exposed a bug in
      lib/eal/riscv/include/rte_vect.h where the alignment
      specified was reduced to 8 for xmm_t.

Please comment, subject to the outcome I will submit further series for
lib/*

Thanks
