Rollup merge of #136530 - Kobzol:x-perf, r=onur-ozkan

Implement `x perf` directly in bootstrap

Discussed [here](https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Turning.20.60x.20perf.60.20into.20a.20first.20class.20command).

Implementing the command directly in bootstrap let's us correctly build the compiler toolchain based on input arguments (such as include rustdoc in the toolchain [only] when needed), and it also makes the CLI interface nicer.

+You can use the `./x perf <command> [options]` command to use this integration.
 
 You can use normal bootstrap flags for this command, such as `--stage 1` or `--stage 2`, for example to modify the stage of the created sysroot. It might also be useful to configure `config.toml` to better support profiling, e.g. set `rust.debuginfo-level = 1` to add source line information to the built compiler.
