Move all unused functions from catalyst-client to lambdas

[menduz]

Many functions present in the catalyst-client are only used by lambdas.

To name a few, we have pipeContent and fetchContentStatus.

In order to provide better APIs for clients, only reused functions should live in the shared client to lower the complexity of the solution and the libraries involved.

These are the functions we need to check:

buildEntity
buildEntityWithoutNewFiles
fetchEntitiesByPointers
fetchEntitiesByIds
fetchEntityById
fetchAuditInfo
fetchContentStatus
downloadContent
isContentAvailable
pipeContent
deployEntity
deploy
getContentUrl

fetchProfiles
fetchWearables
fetchOwnedWearables
fetchOwnedThirdPartyWearables
fetchEmotes
fetchOwnedEmotes
fetchOwnedThirdPartyEmotes
fetchCatalystsApprovedByDAO
fetchLambdasStatus
getLambdasUrl
