base.bbclass: Introduce PACKAGECONFIG_CONFARGS variable

* add separate variable for configuration options generated from
  PACKAGECONFIG setting, this helps other bbclasses and recipes
  to take advantage of PACKAGECONFIG mechanism, without including
  other options from EXTRA_OECONF
* e.g. meta-qt5 recipes are abusing EXTRA_OECONF to get options
  from PACKAGECONFIG:
  EXTRA_QMAKEVARS_PRE +=
  but with
  conf/distro/include/no-static-libs.inc
  it means getting --disable-static as invalid option inside
  EXTRA_QMAKEVARS_PRE as reported by Alexandre Belloni who tried
  to use poky with meta-qt5.
* once we migrate all bbclasses and recipes to PACKAGECONFIG_CONFARGS
  we should also restrict EXTRA_OECONF append only to autotools.bbclass
  like I did for cmake.bbclass
