### Godot version

4.0.beta14

### System information

windows 10, gles 3, nvidia graphics

### Issue description

SCREEN_TEXTURE  was dropped in beta 14. The suggested replacement is to use ```uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmaps;```, but filter_linear_mipmaps is not recognized as a valid shader type hint and a shader using it fails to compile.

### Steps to reproduce

Create a canvas item shader and use the filter_linear_mipmaps type hint with a sampler2D uniform.

### Minimal reproduction project

N/A
PropertyInfo pi;
	switch (p_uniform.type) {
		case ShaderLanguage::TYPE_VOID:
			pi.type = Variant::NIL;
			break;
		case ShaderLanguage::TYPE_BOOL:
			if (p_uniform.array_size > 0) {
				pi.type = Variant::PACKED_INT32_ARRAY;
			} else {
				pi.type = Variant::BOOL;
			}
			break;
		case ShaderLanguage::TYPE_BVEC2:
			if (p_uniform.array_size > 0) {
				pi.type = Variant::PACKED_INT32_ARRAY;
			} else {
				pi.type = Variant::INT;
				pi.hint = PROPERTY_HINT_FLAGS;
				pi.hint_string = "x,y";
			}
			break;
		case ShaderLanguage::TYPE_BVEC3:
			if (p_uniform.array_size > 0) {
				pi.type = Variant::PACKED_INT32_ARRAY;
			} else {
				pi.type = Variant::INT;
				pi.hint = PROPERTY_HINT_FLAGS;
				pi.hint_string = "x,y,z";
