feat: deprecate team transfer, add sharing hooks

[keithharvey]

The idea is to let LUA take over the team transfer logic, and to deprecate the engine's team transfer logic.

• followed the breadcrumbs for everything CHANGETEAM_REASON and deprecated all call paths.
• added new SYNCED_ACTION_FALLBACKS for specific actions (income happens from reclaim, overflow happens)
• the goal is no breaking changes.

tl;dr I made #2529, #2530, #2531 and #2532 and I think these should allow you to do everything you want.

• NetResourceTransfer is somewhat redundant with AllowResourceTransfer. The caveat is that there's two places AllowResourceTransfer can be called from, synced Lua and manual sharing, so you can't tell which is which. I think this is better solved by making it not called from synced Lua, since it can still be called manually if needed (but usually synced Lua wouldn't do silly changes it would later block itself?) and that guarantees that all calls come from manual requests. This is achieved by Spring.ShareTeamResource no longer triggers AllowResourceTransfer #2531.
• similarly NetShareTransfer is mostly redundant with AllowUnitTransfer but you can't tell whether it came from manual individual share, manual "give everything" or /take. I think the best approach here is to extend the "allow take" modrule to "give everything" since they overlap heavily and on some level are the same thing (if people disagree it can also just be a separate bool). See Add system.allowGiveawayResign to block "resign and give everything to X" #2532.
• PR description says that there's now some way to handle resource overflows but I can't find it in the code. Anyway I think that's best handled by Add 'system.nativeExcessSharing' modrule #2529 and Add gadget:TeamResourceExcess(teamID, metal, energy) -> bool #2530.
• income from reclaim is already doable in Lua by setting reclaim efficiency to 0 and using Allow{Unit,Feature}BuildStep, or UnitDestroyed with weaponDefID == reclaimed.
• Spring.ChangeTeamWithReason is already doable entirely in Lua as per refactor: move /take and /give to LUA #2423 (comment), if you're not sure how to translate that e.g. into BAR then I could make a little example PR there too
• there's some /give change, but that is unrelated to /take so shouldn't be touched.
• there's also some /capture change. I'm not sure what it is about, if it's about this comment then what I meant by "capture handling" was not a text action but a Lua reimplementation of the mechanics behind the CMD_CAPTURE unit order, including the application and tracking of capture buildpower.
• there's a bunch of other somewhat chaotic changes, these would ideally be individual PRs if desired.

Nah sorry I meant to remove that entirely.

there's also some /capture change. I'm not sure what it is about, if it's about #2423 (comment) then what I meant by "capture handling" was not a text action but a Lua reimplementation of the mechanics behind the CMD_CAPTURE unit order, including the application and tracking of capture buildpower.

Yes, I'm working on the re-implementation of the CAPTURE mechanics.

income from reclaim is already doable in Lua by setting reclaim efficiency to 0 and using Allow{Unit,Feature}BuildStep, or UnitDestroyed with weaponDefID == reclaimed.

Cool.

some way to handle resource overflows

Whoops you're right that didn't make it in but that sounds like it might be OK: https://github.com/beyond-all-reason/Beyond-All-Reason/pull/5667/files#diff-d445230470af67515fb8e9687ea31988696c94e85a331a22ad66ebcf481f85a8R33
