Remove inline commands for dropping objects

[corivera]

For #25366

We already have Drop commands in the context menu, so the inline commands are unnecessary and can be clicked accidentally.

I would suggest just removing the drop DB but leaving the rest - it's much more common that someone will be dropping an object and having to open up the context menu and find the entry can be annoying.

@Charles-Gagnon We opted to remove all of them to handle the whole class of potential "I accidentally dropped X" issues

Yup, also ran this by @erinstellato-ms and she's good with removing all the drop icons and having them only available via right-click

Build failure looks to be network related. I'll go ahead and merge this
