* Usage:
	# VC Params Type: (Note - "ultimate_google_fonts_style" param must be next to "ultimate_google_fonts" param only)
		1) ultimate_google_fonts - for dropdown of google fonts in collection
			For Ex -
			array(
				"type" => "ultimate_google_fonts",
				"heading" => __("Font Family", "smile"),
				"param_name" => "heading_font"
			),
		2) ultimate_google_fonts_style - for respective google font style or default style
			For Ex -
			array(
				"type" => "ultimate_google_fonts_style",
				"heading" 		=>	__("Font Style", "smile"),
				"param_name"	=>	"heading_style"
			),
	# In respective comoponent shortcode process function
		1) Get font family -
			For Ex -
			$font_family = get_ultimate_font_family($heading_font);
		2) Get font style -
			For Ex -
			$font_style = get_ultimate_font_style($heading_style);
			// deprecated since 3.7.0 - automatically detected font and enqueue accordingly
		3) Enqueue the respective fonts - Note send number of font param as a parameter in array
			For Ex -
			$args = array(
				$heading_font
			);
			enquque_ultimate_google_fonts($args);
