mldev: introduce data type conversion functions

Introduced data type conversion functions with support for
user defined scale factor and zero-point. Updated library
functions to support asymmetric / affine conversion for
integer types.

Now that DPDK provides such bit count functions, make use of them.

This patch was prepared with a "brutal" commandline:

Now that DPDK provides such bit count functions, make use of them.

This patch was prepared with a "brutal" commandline:

$ old=__builtin_clzll; new=rte_clz64;
git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"
$ old=__builtin_clz; new=rte_clz32;

git grep -lw $old :^lib/eal/include/rte_bitops.h |
xargs sed -i -e "s#\<$old\>#$new#g"

Then inclusion of rte_bitops.h was added were necessary.

mldev: fix Arm build with NEON and GCC 4.8.5

Since bfloat16 intrinsics are not supported on all ARM platforms
that support NEON, bfloat16 routines are moved to separate files.
This would enable using scalar implementation for bfloat16 on
unsupported ARM platforms.
