Width type checks with FMT_COMPILE()

[OnurKader]

I assume it's the same problem with #1715, so feel free to close this if it's a duplicate

	std::string str = fmt::format(FMT_COMPILE("{:>{}}"), "Whoops", 15);
	fmt::print("Wow: {}\n", str);

Results in a runtime exception

terminate called after throwing an instance of 'fmt::v7::format_error'
  what():  width is not integer

Dynamic width wasn't implemented in FMT_COMPILE but it is as of 54daa08.
