Provide __rte_section(name) macro that allocates and names a section
or segment that works with both MSVC and GCC.
Update RTE_TRACE_POINT_REGISTER with __rte_section("__rte_trace_point")
instead of __attribute__(section(name)) so the macro may be compatibly
expanded when using MSVC.

v2:
* Define an internal macro __rte_section for the trace point
allocation and use it in RTE_TRACE_POINT_REGISTER instead of
duplicating original macro expansion for MSVC.
