[clang-format] New flag - BraceWrapping.AfterExternBlock
Summary:
Bug: https://bugs.llvm.org/show_bug.cgi?id=34016 - **"extern C part"**
**Problem:**
Due to the lack of "brace wrapping extern" flag, clang format does parse the block after **extern** keyword moving the opening bracket to the header line always!
**Patch description:**
A new style added, new configuration flag - **BraceWrapping.AfterExternBlock** that allows us to decide whether we want a break before brace or not.
