[chore] Allow OTTL pdata Map setters to take raw map

[TylerHelmuth]

Description

To be consistent, we should try treating raw maps and pcommon.Map the same. Updates all the setters that were expecting a pcommon.Map to also allow a raw map to set the value

Testing

unit tests

[edmocosta]

We could maybe add a new function into the internal/ctxutil package for handling this common logic, E.g.:

func SetMap(target pcommon.Map, val any) error {
	if cm, ok := val.(pcommon.Map); ok {
		cm.CopyTo(target)
		return nil
	}
	if rm, ok := val.(map[string]any); ok {
		return target.FromRaw(rm)
	}
	return nil
}
