Rollup merge of rust-lang#152326 - Kobzol:remove-compiler-adhoc-group, r=wesleywiser

Remove the compiler adhoc group

Since triagebot now allows configuring rotation mode through a specific team.

Original review rotation:

```toml
compiler = [
    "@BoxyUwU",
    "@chenyukang",
    "@davidtwco",
    "@eholk",
    "@fee1-dead",
    "@fmease",
    "@jackh726",
    "@jieyouxu",
    "@jdonszelmann",
    "@JonathanBrouwer",
    "@madsmtm",
    "@mati865",
    "@Nadrieril",
    "@nnethercote",
    "@oli-obk",
    "@petrochenkov",
    "@SparrowLii",
    "@TaKO8Ki",
    "@tiif",
    "@WaffleLapkin",
    "@wesleywiser",
]
```

I went through all the remaining members of t-compiler now and set their `compiler` team rotation to be off, to match the original state. You can check it with `team-stats compiler`.
