[PATCH] provide Windows/MSVC lcore macros

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

Provide MSVC compatible macros RTE_DEFINE_PER_LCORE and
RTE_DECLARE_PER_LCORE that expand appropriately for Windows/MSVC

NOTICE:

It is intentional that devtools/checkpatches.pl generates an error
about parenthesis to allow comparison with clang/gcc versions of
these macros which also do not have the parenthesis.

```
