Clang-format: add finer-grained options for putting all arguments on one line

Clang-format: add finer-grained options for putting all arguments on one line

Summary:
Add two new options,
AllowAllArgumentsOnNextLine and
AllowAllConstructorInitializersOnNextLine.  These mirror the existing
AllowAllParametersOfDeclarationOnNextLine and allow me to support an
internal style guide where I work.  I think this would be generally
useful, some have asked for it on stackoverflow:
