Macro error message are now always displayed in standalone mode even when macro is used inline

See XWIKI-11390 and especially the comment by Guillaume explaining the alternative.

Note that the rendering code handles inline and standalone macros differently already so the fix in XWIKI-11390 was negating it, see https://github.com/xwiki/xwiki-rendering/blob/41f1413266379b6c11776d66663603317dc1c3e6/xwiki-rendering-transformations/xwiki-rendering-transformation-macro/src/main/java/org/xwiki/rendering/internal/transformation/macro/MacroErrorManager.java#L77-L77
