Fix parachain upgrade scheduling when done by the owner/root#3341
Conversation
When using `schedule_code_upgrade` to change the code of a parachain in the relay chain runtime, we had already fixed to not set the `GoAhead` signal. This was done to not brick any parachain after the upgrade, because they were seeing the signal without having any upgrade prepared. The remaining problem is that the parachain code is only upgraded after a parachain header was enacted, aka the parachain made some progress. However, this is quite complicated if the parachain is bricked (which is the most common scenario why to manually schedule a code upgrade). Thus, this pull request replaces `SetGoAhead` with `EnactUpgradeDirectly` to signal to the logic that we don't want to set the go ahead signal and that we want to replace the current parachain code directly without waiting for some progress of the parachain.

Nit: Why is this not a match? Would be a tad more future proof in case someone introduces more variants.

This match arm here seems to be doing what needs to be done for UpgradeStrategy::ApplyAtExpectedBlock.

LOL. I'm an idiot. Broken it with one of the last commits.

The strategies are either `SetGoAheadSignal` or `ApplyAtExpectedBlock`. `SetGoAheadSignal` sets the go ahead signal as before and awaits a parachain block. `ApplyAtExpectedBlock` schedules the upgrade and applies it directly at the `expected_block` without waiting for the parachain to make any kind of progress.
