Display grotto and GFF names on entry/pause

[djevangelia]

There was a request on Discord for information in grottos which grotto it is.
While waiting for the spawning signs on scene init ability, this setting displays the grotto name when entering a grotto or a Great Fairy fountain and when pausing.

Notes:

• Shuffling grottos must be enabled.
• It shows the Great Fairy info regardless of whether shuffling interiors is enabled. It's not possible to enable Great Fairy info without shuffling grottos. No suggestions on what to do here, if they should be split up etc. I'm kinda assuming that someone who shuffles grottos probably also shuffles Great Fairies.
• To my knowledge and looking at code music names are shown in the top so they shouldn't overlap, but I didn't actually test this.
• I haven't tested other fonts/sizes/colors etc. I hope that the pause menu display is good enough for cases where the on-entry text is hard to read due to background etc.
• It's only English. しょうがない, as they say.

Testing

Tested in ares old nightly build and Project64 3.0.1.

That's outside of the CRT safe area and will be cut off on certain sets.

Do you have measurements for the safe area?

Here is a screenshot from a different PR (moving the triforce hunt counter at the bottom of this screenshot up (#2084)):

Red is likely to be cut off, yellow can be cut off so no important information should be there, green is the safe area that should always be displayed on all sets.

I pushed it up a bit. It looks a bit ugly when pausing but think it's ok for those who choose to play with this setting enabled.
It could of course also be placed in one of the D-pad info tabs, I mostly just want the option to be there in some form.

Might be worth making sure there aren't any buffer overflow issues with this while paired with displaying song names. I think we had issues with that in the past

That was when we were still adding to the game's own display list buffers. As long as this is using the randomizer display list buffer it shouldn't be an issue? Worth testing in case the buffer sizes need increased again though I guess.

Indeed it uses the rando_overlay_db.
