LADX: combine warp options

[threeandthreee]

What is this fixing or adding?

LADX has two QoL warp options as toggles, but one only works if the other is enabled. This makes a single option combining both.

How was this tested?

Was added very early in the ladx beta process, has had a lot of playtesting.

This should probably mark both WarpImprovements and AdditionalWarpPoints as Removed. For an example https://github.com/ArchipelagoMW/Archipelago/blob/main/worlds/dark_souls_3/Options.py#L420

Tested in the Asyncs, done the poll, had lots of Syncs, you know the drill.

One thing I'd love is if the old options could be converted by YAMLs into the new ones (to make old YAMLs forward compatible) but then when would it stop I guess. The current Beta apworld v9.1 has this fwiw.

For the record, I think "yaml backwards compatibility" is one of those QoL features that we should as devs draw a strict boundary against - Unless it can be solved by aliases, or a one-or-two-line from_any override, it just makes our code worse and more complicated
