clang-format: Add configuration option to allow function parameters to be on new lines in function declarations

[Fanteria]

Currently, there is an option BreakFunctionDefinitionParameters to control line breaks for function definitions.
It would be useful to have a similar option, for example, BreakFunctionDeclarationParameters, to control line breaks in declarations as well.

Example:

void FunctionDeclaration(
    int a,
    int b);
