capabilities: Use AllCapabilities() instead of manual string capabilities

app/wasm.go (Useful for when we bump to wasmvm 1.3)
https://github.com/CosmWasm/wasmd/blob/6d770a5a9eea3474851413654833425ab8175754/app/wasm.go#L11

Importing app may be bleh, maybe this should be in types there?

not possible with it being in app, need to have it be upstream in wasmvm or wasmd types or something

Hey @Reecepbcups!

Where would you need this function in wasmd? Could you send a PR to wasmd? It cannot be in wasmvm because what this list is saying semantically is: "all the capabilities that this backend is providing". Bumping to a newer wasmvm does not mean a capability is added.

From 2.0 onwards, wasmvm will accept a list of strings instead of a coma separated list. So we should work towards the []string type for all new code.

@webmaster128 Thank you, I have no clue what problems I was having that day but works now on wasmd v0.45! May have just been an editor false positive for an import or something

Okay, nice. Then we only have to update the comment of AllCapabilities which is misleading.
