OvmfPkg: require GCC48 or later

We're about to remove BaseTools support for GCC44..GCC47. Reject those gcc
versions cleanly in "OvmfPkg/build.sh". In "OvmfPkg/README", upgrade any
mentions of the same gcc versions to GCC48.

No GCC44..GCC47 references remain under OvmfPkg after this patch.

 If you build with the UNIXGCC toolchain, then debugging will be disabled

 due to larger image sizes being produced by the UNIXGCC toolchain. The

 If you must use UNIXGCC, then you can override the build options for

 particular libraries and modules in the .dsc to re-enable debugging
