bump bootstrap dependencies
This PR removes hard-coded patch versions, updates bootstrap's dependency stack to recent versions (some of the versions were released 3-4 years ago), and removes a few dependencies from bootstrap.
Removed dependencies:
add more niches to rawvec
Previously RawVec only had a single niche in its `NonNull` pointer. With this change it now has `isize::MAX` niches since half the value-space of the capacity field is never needed, we can't have a capacity larger than isize::MAX.
As bootstrap locks its entire build directory, parallel bootstrapping
for anything becomes impossible. This change enables developers to bypass
the locking mechanism when it is unnecessary for their specific use case.

Run tidy license checker on more workspaces
The license checker didn't run on several workspaces before this PR. The same applied to the "external package sources" check. There were also two missing lockfiles which I have added now.
add bootstrap flag `--skip-stage0-validation`
This change introduces the `--skip-stage0-validation` flag, which permits the use of any desired version of the stage0 compiler without verifying its version.
Additionally, stage0 compiler validation check is reverted(#115103) to its default enabled state.
Helps to #115065

Rewrite gdb pretty-printer registration
Currently, the Rust pretty-printers are registered in gdb using the uninformative name "lookup":
(gdb) info pretty-printer
global pretty-printers:
[...]
objfile /home/tromey/[...]
lookup
It's nicer for users if the top-level registration is given a clear name. Additionally, gdb lets users individually enable and disable specific printers, provided they are registered correctly.
This patch implements both these ideas. Now the output looks like:
(gdb) info pretty-printer
global pretty-printers:
[...]
objfile /home/tromey/[...]
rust
StdArc
StdBTreeMap
StdBTreeSet
StdCell
StdHashMap
StdHashSet
StdNonZeroNumber
StdOsString
StdRc
StdRef
StdRefCell
StdRefMut
StdSlice
StdStr
StdString
StdVec
StdVecDeque
This change introduces the --skip-stage0-validation flag,
which permits the use of any desired version of the stage0
compiler without verifying its version.

GDB 14 has a "gdb.ValuePrinter" tag class that was introduced to let
GDB evolve the pretty-printer API. Users of this tag are required to
hide any local attributes or methods. This patch makes this change to
the Rust pretty-printers. At present this is just a cleanup,
providing the basis for any future changes.

Raise minimum supported Apple OS versions
This implements the proposal to raise the minimum supported Apple OS versions as laid out in the now-completed MCP (https://github.com/rust-lang/compiler-team/issues/556).
As of this PR, rustc and the stdlib now support these versions as the baseline:
- macOS: 10.12 Sierra
- iOS: 10
- tvOS: 10
- watchOS: 5 (Unchanged)
In addition to everything this breaks indirectly, these changes also erase the `armv7-apple-ios` target (currently tier 3) because the oldest supported iOS device now uses ARMv7s. Not sure what the policy around tier3 target removal is but shimming it is not an option due to the linker refusing.
[Per comment](https://github.com/rust-lang/compiler-team/issues/556#issuecomment-1297175073), this requires a FCP to merge. cc `@wesleywiser.`
in commit 8dd0ec6, the `GDB_ARGS` variable was split across 3 lines. However, extra quotes were added to each line, such that the shell interprets the 3 lines as space separated strings, and tries to execute the latter two lines.
This commit simply removes the extra quotes.
Add support for tidy linting via external tools for non-rust files
This change adds the flag `--check-extras` to `tidy`. It accepts a comma separated list of any of the options:
* py (test everything applicable for python files)
* py:lint (lint python files using `ruff`)
* py:fmt (check formatting for python files using `black`)
* shell or shell:lint (lint shell files using `shellcheck`)
Specific files to check can also be specified via positional args. Examples:
* `./x test tidy --check-extras=shell,py`
* `./x test tidy --check-extras=py:fmt -- src/bootstrap/bootstrap.py`
* `./x test tidy --check-extras=shell -- src/ci/*.sh`
* Python formatting can be applied with bless: `./x test tidy --ckeck-extras=py:fmt --bless`
`ruff` and `black` need to be installed via pip; this tool manages these within a virtual environment at `build/venv`. `shellcheck` needs to be installed on the system already.

This PR doesn't fix any of the errors that show up (I will likely go through those at some point) and it doesn't enforce anything new in CI. Relevant zulip discussion: https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/Other.20linters.20in.20CI

Add support for allocators in `Rc` & `Arc`
Adds the ability for `std::rc:Rc`, `std::rc::Weak`, `std::sync::Arc`, and `std::sync::Weak` to live in custom allocators
Make GDB Python Pretty Printers loadable after spawning GDB, avoiding required `rust-gdb`
Fixes#111961
Makes the Python pretty printer library source'able from within GDB after spawn, making the wrapper script `rust-gdb` become not the required approach to use the pretty printer library.
Allows for integration into GUI:s that wrap GDB extremely easy. The previous design complicates this feature.
Makes the Python pretty printer library source'able from within
GDB after spawn.
This makes `rust-gdb` not the required approach. It also provides the possibility
for GUI:s that wrap GDB, to debug Rust using the pretty printer library; as well
as other projects such as for instance Pernosco, which previously was not possible.
This won't introduce any new unexpected behaviors for users of `rust-gdb`
Add other workspaces to `linkedProjects` in rust_analyzer_settings
This makes go-to-definition, etc. work in cg_clif, cg_gcc, rust-analyzer, and src/tools/x.
