bootstrap: use the same version number for rustc and cargo

Historically the stable tarballs were named after the version number of
the specific tool, instead of the version number of Rust. For example,
both of the following tarballs were part of the same release:

    rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz
    cargo-0.49.0-x86_64-unknown-linux-gnu.tar.xz

PR #77336 changed the dist code to instead use Rust's version number for
all the tarballs, regardless of the tool they contain:

    rustc-1.48.0-x86_64-unknown-linux-gnu.tar.xz
    cargo-1.48.0-x86_64-unknown-linux-gnu.tar.xz

Because of that there is no need anymore to have a separate `cargo`
field in src/stage0.txt, as the Cargo version will always be the same as
the rustc version. This PR removes the field, simplifying the code and
the maintenance work required while producing releases.

Make the libstd build script smaller

Of all sysroot crates currently only compiler_builtins, miniz_oxide and std require a build script. compiler_builtins uses to conditionally enable certain features and possibly compile a C version ([source](https://github.com/rust-lang/compiler-builtins/blob/63ccaf11f08fb5d0b39cc33884c5a1a63f547ace/build.rs)), miniz_oxide only uses it to detect if liballoc is supported as the MSRV is 1.34.0 instead of the 1.36.0 which stabilized liballoc ([source](https://github.com/Frommi/miniz_oxide/blob/28514ec09f0b1ce74bfb2d561de52a6652ce377a/miniz_oxide/build.rs)). std now only uses it to enable `freebsd12` when the `RUST_STD_FREEBSD_12_ABI` env var is set, to determine if `restricted-std` should be set, to set the `STD_ENV_ARCH` env var identical to `CARGO_CFG_TARGET_ARCH`, and to unconditionally enable `backtrace_in_libstd`.

If all build scripts were to be removed, it would be possible for rustc to completely compile it's own sysroot. It currently requires a rustc version that already has an available libstd to compile the build scripts. If rustc can completely compile it's own sysroot, rustbuild could be simplified to not forcefully use the bootstrap compiler for build scripts.

RFC-2229: Implement Precise Capture Analysis

### This PR introduces
- Feature gate for RFC-2229 (incomplete) `capture_disjoint_field`
- Rustc Attribute to print out the capture analysis `rustc_capture_analysis`
- Precise capture analysis

### Description of the analysis
1. If the feature gate is not set then all variables that are not local to the closure will be added to the list of captures. (This is for backcompat)
2. The rest of the analysis is based entirely on how the captured `Place`s are used within the closure. Precise information (i.e. projections) about the `Place` is maintained throughout.
3. To reduce the amount of information we need to keep track of, we do a minimization step. In this step, we determine a list such that no Place within this list represents an ancestor path to another entry in the list.  Check rust-lang/project-rfc-2229#9 for more detailed examples.
4. To keep the compiler functional as before we implement a Bridge between the results of this new analysis to existing data structures used for closure captures. Note the new capture analysis results are only part of MaybeTypeckTables that is the information is only available during typeck-ing.

### Known issues
- Statements like `let _ = x` will make the compiler ICE when used within a closure with the feature enabled. More generally speaking the issue is caused by `let` statements that create no bindings and are init'ed using a Place expression.

### Testing
We removed the code that would handle the case where the feature gate is not set, to enable the feature as default and did a bors try and perf run. More information here: #78762

This has been slowly in the works for a while now.

Fix setting inline hint based on `InstanceDef::requires_inline`

For instances where `InstanceDef::requires_inline` is true, an attempt
is made to set an inline hint though a call to the `inline` function.
The attempt is ineffective, since all attributes will be usually removed
by the second call.

Fix the issue by applying the attributes only once, with user provided
attributes having a priority when provided.
