Control loading FontAwesome for vector style

[mahmoudadel54]

Description

This issue is for enhancement the way of loading fontawesome for vector style for icons implemented here:

MapStore2/web/client/utils/styleparser/StyleParserUtils.js

Lines 920 to 935 in 831eab5

	return loadFontAwesome()
	.then(
	() => new Promise((resolve) => {
	if (marks.length > 0 || icons.length > 0) {
	Promise.all([
	...marks.map(getWellKnownNameImageFromSymbolizer),
	...icons.map(getImageFromSymbolizer)
	]).then((images) => {
	resolve(images);
	});
	} else {
	resolve([]);
	}
	})
	);
	};

The current implementation is loading the fontawesome whatever the data has icons or not.

The main use case for this issue is [When uploading shapefiles with vector data, there's no need to load the FontAwesome style,] because:

• if there is a project uses MS submodule and this project uses fontawesome package [latest version '6'] in its UI rather than MS one [version 4.7]
• If this fontawesome in MS loaded by calling the above function, the appearance of project icons will be changed in their appearance due to loading old fontawesome style
• the shapefiles don't contain any icons that require loading the FontAwesome style like the implemented one

So we need:

• Control the loading of FontAwesome of vector style through a configuration setting (cfg) flag in localConfigs if the project makes sure that there will not be any need for loading fontAwesome for vector style it should be false and by default it is true.
• Implement a check to ensure that if no icons are needed, the FontAwesome style is not loaded.
