`rustc` allows passing in predefined target triples as well as JSON
target specification files. This change allows bootstrap to have the
first inkling about those differences. This allows building a
cross-compiler for an out-of-tree architecture (even though that
compiler won't work for other reasons).
Even if no one ever uses this functionality, I think the newtype
around the `Interned<String>` improves the readability of the code.
Also, promote defaults.run.shell from inside only the primary jobs to
the top level.
The src/ci/exec-with-shell.py wrapper script was formerly used to change
out the shell mid-job by intercepting a CI_OVERRIDE_SHELL environment
variable. Now, instead, we just set `bash` as the global default across
all jobs, and we also delete the exec-with-shell.py script.

This will render the src/ci/exec-with-shell.py script more or less
useless, but we're going to replace that by just using the system bash
instead.

As a none-native speaker I stumbled upon this, looked it up and couldn't find a phrase, so I made my own assumption that "in any way" was meant (which is the meaning I would've deduced anyway)
Bump version to 1.47
This also bumps to a more recent rustfmt version, just to keep us relatively up to date (though almost nothing has changed in rustfmt we use beyond bumps to the parser infra). No formatting changes as a result of this.

Add build support for Cargo's build-std feature.
This makes some changes to the standard library to make it easier to use with Cargo's build-std feature. The primary goal is to make it so that Cargo and its users do not need to know which crates to build and which features to use for every platform.
Conditional cfgs are adjusted so that there is usually a fall-through for unsupported platforms. Additionally, there is a "restricted-std" feature to mark `std` as unstable when used with build-std on no_std platforms. There is no intent to stabilize this feature for the foreseeable future.
This borrows some of the implementation for wasm which already does what this needs. More code sharing can be done with some other platforms (there is a lot of duplication with cloudabi, hermit, and sgx), but I figure that can be done in a future PR.
There are some small changes to stable behavior in this PR:
- `std::env::consts::ARCH` on asmjs now reports "wasm32", to match its actual architecture.
- Some of the wasm error messages for unsupported features report a slightly different error message so that the code can be reused.
There should otherwise not be any changes to how std is built for distribution via bootstrap.
This does not yet support all platforms when used with build-std.
- It doesn't work with 16-bit targets (hashbrown does not support that).
- It does not work with JSON spec targets.
- In particular, all target triple snooping will need to be replaced with appropriate target option checking.
- Switching to gimli (#73441) will make cross-building *much* easier.
- There are still a ton of issues on the Cargo side to resolve. A big one is panic strategy support.
Future PRs are intended to address some of these issues.
