Change AlignAfterOpenBracket in .clang-format to BlockIndent

[Yay295]

Currently in Python when a function declaration is split across multiple lines, the closing parenthesis is on the same level as the def.

Pillow/src/PIL/Image.py

Lines 3484 to 3488 in c250a44

	def register_open(
	id,
	factory: Callable[[IO[bytes], str | bytes], ImageFile.ImageFile],
	accept: Callable[[bytes], bool | str] | None = None,
	) -> None:

However currently in C the closing parenthesis is on the same line as the last argument.

static int
decode_bcn(
    Imaging im,
    ImagingCodecState state,
    const UINT8 *src,
    int bytes,
    int N,
    int C,
    char *pixel_format) {

It's the same with function calls as well.

This change changes the C style to match the Python style.
