Add build.info.flags property in platform.txt

Create build.info.flags property to factorize some recipe
It contains:
Standard Arduino defines:
  -DARDUINO={runtime.ide.version}
  -DARDUINO_{build.board}
  -DARDUINO_ARCH_{build.arch}

MCU serie:
  -D{build.series}

New one to know the board name
  -DBOARD_NAME="{build.board}"
