[Feature] Improve SollCall return type encoding

[rouzwelt]

Component

sol-types, sol! macro

Describe the feature you would like

right now when we have somethingReturn and want to potentially abi encode it back, there is no direct way, one way is to use somethingCall::abi_encode_returns() but this wont accept the somethingReturn value directly and throws errors for impl bounds are not met.
a workaround is to deconstruct the somethingReturn value when calling the abi encode like:
somethingCall::abi_encode_returns(&(somethingReturn.field1, somethingReturn.field2, ...))

but this is not a really good API, so an improvement would be appreciated so we can just abi encode a return type as normally we encode any SollCall value.
