Lluc Pares 2005b5c44a RichTextLabel: decouple meta cursor from underline 
This commit decouples the type of cursor used when the underline
of meta tag is set to False. Previous to this commit setting the
meta underline to false in the RichTextLabel would also make it
show the arrow cursor instead of the hand cursor.

Making the meta tag with no underline should not have any effect
on the type of cursor, since the text will still be clickable it
should be expected to have a hand cursor.

The same behavior is seen in other languages, like HTML+CSS, where
the setting "text-decoration" to "none" for the links, disables
the underline but maintains the clickable cursor.

Fixes godotengine/godot-proposals#3193
