[Maps] Fit to data doesn't work in TMS

[kindsun]

Fit to data doesn't currently do anything in TMS. It's not entirely clear if this should be an option for this layer type. We should consider graying it out, removing it, or if it is supposed to do something, connecting that logic.

To reproduce:

1. Go to Add layer > Tile map service
2. Add the following URL: http://c.tile.stamen.com/watercolor/{z}/{x}/{y}.jpg
3. Skip atrribution and Add layer
4. Click on the new layer in the TOC and attempt to Fit to data

Agreed that UX is wonky here. Graying out when a layer-type does not support fit2 layer (e.g. in the case of a raster layer) makes sense to me.

@aaronjcaldwell @thomasneirynck I actually like removing it, because it will never be enabled on this menu (for this layer type)... or would it be if the tile layer had a small extent?

Arguing against myself -- it is such a commonly used menu; that muscle memory and consistency of position might be more important.

@kmartastic I guess I'm more in this camp. All of the options except this one are consistent and applicable to all other layer types so seems easiest just to keep the same options but grey this one out here. That said, I'm not passionate about it so happy to jump on the removal bandwagon if anyone feels strongly.

@miukimiu What do you think?

Consistent position on layer menu, but disabled.
vs
A disabled menu option that can never be enabled given it's context (layer type doesn't support option).
