Add info tooltip to inlay hints

Looks good, just need to patch up assertions on the tooltips in the tests. I guess they're all the same unless we're testing the permutations of the enable/disable mechanism.

Two issues:

The message overrides the original tooltip (which currently only happens when hint gets truncated):

Long tooltip:

Short tooltip:

I think when InlayHint provides a Tooltip we should put a separator between Inlay Hint tooltip and info on how to hide inlay hints (like the separator between current tooltip & "double click to insert")

The message is very VsCode/Ionide centric:

• Commands are required on client to change settings
• Assumes VsCode Behaviour (-> existence of offUnlessPressed behaviour for Inlay Hints)
• Shortcut is for VsCode

I think we should move the info to the client side:
Instead of disableLongTooltip to disable info, the client can push additionalInfo for InlayHints to FSAC, which FSAC then adds below the Inlay Hint tooltip (or can extension in VSCode add text on its own to existing tooltips?)
-> Ionide provides info message about how to disable Inlay Hints with its Ionide-commands, while other clients don't get the Ionide-specific message

This is a fair point - I've changed the default value for disableLongTooltip to false so all other clients will get standard tooltips. We will override the default on the Ionide side to get the long one by default in VSCode. I guess we could do the design you've suggested (with the Client defining the long tooltip content) - but TBF, I'm not convinced it's worth the effort right now; I'd rather merge this ASAP and finally do a new Ionide release.
