Pull request overview

This PR refactors the entity-to-string conversion API by consolidating multiple entity-specific methods (MethodToString, FieldToString, PropertyToString, EventToString) into a unified EntityToString method. The refactoring introduces a new ILAmbience class that handles IL-style formatting of types and entities using ConversionFlags instead of multiple boolean parameters.

Key changes:

• Introduced ILAmbience class with ConvertSymbol and ConvertType methods to handle formatting
• Replaced boolean parameters in API methods with ConversionFlags enum for more granular control
• Deprecated entity-specific methods in favor of unified EntityToString API
• Migrated EscapeName utility methods from Language class to ILAmbience

• Changing EnumNameCollection from a class to a struct causes issues with the collection initializer syntax used for static readonly fields (lines 102, 118, 127, 136, 143, 1270, 1279, 1418, 1492). When using collection initializers like "new EnumNameCollection() { ... }", the Add method is called on the struct instance. However, since these are static readonly fields, the struct instance is readonly, and calling Add (which modifies the struct) will only modify a temporary copy, leaving the actual field empty. This will cause all enum/flag name lookups to fail silently.

		internal struct EnumNameCollection<T> : IEnumerable<KeyValuePair<long, string>> where T : struct
		{
			List<KeyValuePair<long, string>> names = new List<KeyValuePair<long, string>>();

			public EnumNameCollection()
			{
			}

			public void Add(T flag, string name)
			{
				this.names.Add(new KeyValuePair<long, string>(Convert.ToInt64(flag), name));
			}

			public IEnumerator<KeyValuePair<long, string>> GetEnumerator()
			{
				return names.GetEnumerator();
			}

			System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
			{
				return names.GetEnumerator();
			}
		}
