  Revert "[Support]Look up in top-level subcommand as a fallback when looking options for a custom subcommand (#71975)

…ooking options for a custom subcommand. (#71776)"

This reverts commit b88308b1b4813e55ce8f54ceff6e57736328fb58.

The build-bot is unhappy
(https://lab.llvm.org/buildbot/#/builders/186/builds/13096),
`GroupingAndPrefix` fails after `TopLevelOptInSubcommand` (the newly
added test).

Revert while I look into this (might be related with test sharding but
not sure)

```
