[XCM] Replace Wild(All) for teleports and wherever else possible

[ruseinov]

As the XCM v3 comes in we'd need to fix https://github.com/paritytech/polkadot/blob/53253de77f1649ecbb650df2ec3e29d0d1110a2d/xcm/pallet-xcm/src/lib.rs#L874 and similar occurrences with the new invariants of Wild.

Why? Because we are relying on coefficients to calculate weights, for example here and that turns out way more expensive, because we don't know an exact or approximate number of assets teleported.

It's not clear what coefficients mean from your description, I think what you meant was that we rely on the number of asset classes that is specified in the asset wildcard to calculate weights.

@ruseinov Is this already done?

[KiChjang]

I think this has already been done in cumulus.
