Crash When Applying Color Attribute with Void Function

Reproduce the crash with the Pattern Language snippet and start at pl::core::ast::applyTypeAttributes, identified in the stack trace, then trace how the void result from color(void(1)) is handled. Done means the example no longer crashes when a color attribute calls a void function; add or run a regression check if the repository provides one.

The following code causes ImHex to crash when the color attribute is used with a void function:

fn void(auto t) {
};

struct Struct{
    u32 field [[color(void(1))]];
};

Struct var@ 0;
