[0/9] msvc integration changes

  In accordance with draft plan
http://mails.dpdk.org/archives/web/2023-February/002023.html
introduces conditionally compiled code to enable building with MSVC that
_does not_ require C99/C11 meaning it can be integrated now.

This series covers minimal changes for item #2 in draft plan for EAL
dependencies kvargs, telemetry and consumed EAL public headers.

Note if any patch in the series requires in-depth discussion I'll
detach it from this series for separate submission & more focused
discussion so it doesn't block the entire series.

Tyler Retzlaff (9):
  eal: use rdtsc intrinsic when compiling with msvc
  eal: use rtm and xtest intrinsics when compiling with msvc
  eal: use barrier intrinsics when compiling with msvc
  eal: typedef cpu flag enum as int for msvc
  eal: hide GCC extension based alignment markers
  eal: expand most macros to empty when using msvc
  eal: exclude exposure of rte atomic APIs for MSVC builds
  telemetry: disable json print formatting with msvc
  telemetry: avoid expanding versioned symbol macros on msvc

As I mentionned on the prefetch and byteorder patches, I made some
adjustments while rebasing the series.
Hopefully, I broke nothing.

Series applied, thanks Tyler and reviewers.
