r? cuviper
To decide if internal items should be inlined in a doc page,
check if the crate is itself internal, rather than if it has
the rustc_private feature flag. The standard library uses
internal items, but is not itself internal and should not show
internal items on its docs pages.

[beta] backports
- Consider inner modules to be local in the `non_local_definitions` lint #124539
- Fix bootstrap panic when build from tarball #124668
r? cuviper
This is a workaround for #122758, but it's not clear why 1.79 requires a
more extensive amount of no_inline than the previous release. Seems like
there's something relatively subtle happening here.
Unconditionally call `really_init` on GNU/Linux
This makes miri not diverge in behavior, it fixes running Rust linux-gnu binaries on musl with gcompat, it fixes dlopen edge-cases that cranelift somehow hits, etc.
Fixes#124126
thou hast gazed into this abyss with me:

bootstrap: Document `struct Builder` and its fields
I'm exploring the code of bootstrap and had a bit of a hard time understanding exactly what `Builder` is for at first. I decided to help document it and its field to help future explorers.
bootstrap: Describe build_steps modules
One of my preferred ways to understand source code is to start with its API. This implies the code is documented reasonably accurately, even if it is a private API. The description of one of these modules had not been updated since 2015 and so was both terse and confusing, so I rewrote it. Then I noticed many others went unremarked, so I offered some remarks.
`x vendor`
This PR implements `x vendor` on bootstrap; enabling dependency vendoring without the need for developers to have `cargo` installed on their system (previously, we suggested running `cargo vendor ...` but now we can accomplish the same task with `x vendor`).
In addition, fixes#112391 problem.

bootstrap: Change `global(true)` to `global = true` for flags for consistency
All other arg properties use the `prop = value` style, which makes it slightly annoying to use the `prop(value)` only style for `global`. Change to `prop = value` also for `global` for consistency.
Remove lazycell and once_cell from compiletest dependencies
Use the standard library `OnceLock` instead of third-party equivalents. A macro is used for the regexes to make their initialization less unwieldy.
