Since 1.21.2, vanilla split relative teleportation flags into position and delta/velocity flags into separate enum entries. This highlighted a design flaw in the paper api addition for teleport flags, which just simply mirrored internals while also only being able to apply the delta/velocity part of a flag, given the teleport target is always absolute in the API. This patch proposes to simply no longer expose the non-velocity related flags to the API, instead marking the entire Relative enum as being purely velocity related, as non-velocity related flags are not useful to callers. This was done over simply exposing all internal flags, as another vanilla change to the internal enum would result in the same breakage. The newly proposed API *only* promises that the passed flags prevent the loss of velocity in the specific axis/context, which should be independent enough of vanillas specific implementation of this feature.
