Refactor: getOpponents must be called with second param to ignore leave players in any effects

from 725c29182b661985bc0f9183a9e427cf865d4edd

Due mtg rules:
* end of turn effects of leave player must keep until end of turn (e.g. include leave players for stats calculations and checks)
* one short and other one time effects and SBA must use actual game info (e.g. exclude leave players);

`Game::getOpponents` already support it, but many effects use default method and include leave players. But it must exclude it (see bugs example with Corrupt ability from 725c29182b661985bc0f9183a9e427cf865d4edd);

Possible solutions:
1. Normal: deprecate one param version of getOpponents and replace it by two params version (~700 effects to check, fix example: 58fbfdd5298371333b4c4b4628c40f6ad8ec3c30);
2. Better: make default getOpponents to exclude leave players (it's 99% of all use cases); but it require some tests. Current code fails in one place only `test_BloodchiefAscension_DieBeforeEndTurn`. So such use cases are low tested. Potentially bugged code to check: regexp search `Opponent.+Condition` -- it must setup additional param to include/exclude leave player.

Bugs example:
* #9028

Start with Game::getOpponents and the failing test_BloodchiefAscension_DieBeforeEndTurn. Search for Opponent.+Condition and inspect the effects that call getOpponents without the second parameter, using the linked commits and bug #9028 for context. Done means the chosen getOpponents behavior is applied consistently and the relevant tests pass.
