Changes to OSX JDK8/JDK11 Setup

[babsingh]

• For OSX JDK8, gcc49 is no longer needed. So, gcc49 should be uninstalled from machines: brew uninstall gcc49.
• Changes to mac.sh:
  • Set MACOSX_DEPLOYMENT_TARGET to 10.9.0 for both JDK8 and JDK11 [mac.sh L21 and L62]. In the extensions repos,MACOSX_VERSION_MIN is used to set env var MACOSX_DEPLOYMENT_TARGET and compiler options. MACOSX_VERSION_MIN is set to 10.9.0 for both JDK8 and JDK11.
  • Remove --with-extra-cxxflags=-mmacosx-version-min=10.8 from L41. This will conflict with MACOSX_VERSION_MIN being set to 10.9.0 for JDK11.
  • Update configure options for OSX JDK8 mac.sh::L64:

from:
 export CONFIGURE_ARGS_FOR_ANY_PLATFORM="${CONFIGURE_ARGS_FOR_ANY_PLATFORM} --with-xcode-path=/Applications/Xcode.app --with-openj9-cc=/usr/local/bin/gcc-4.9 --with-openj9-cxx=/usr/local/bin/g++-4.9 --with-openj9-developer-dir=/Applications/Xcode7/Xcode.app/Contents/Developer"

to:
 export CONFIGURE_ARGS_FOR_ANY_PLATFORM="${CONFIGURE_ARGS_FOR_ANY_PLATFORM} --with-xcode-path=/Applications/Xcode.app --with-openj9-cc=/Applications/Xcode7/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang --with-openj9-cxx=/Applications/Xcode7/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ --with-openj9-developer-dir=/Applications/Xcode7/Xcode.app/Contents/Developer"

Note: The above changes should be applied after eclipse-openj9/openj9#3629 is merged.

I was supposed to create the issue in AdoptOpenJDK/openjdk-infrastructure. Thus, closing this issue and creating a new one in AdoptOpenJDK/openjdk-infrastructure. Link to the new issue: adoptium/infrastructure#561.
