feat: Suggest name in completion for let_stmt and fn_param
fix#17780
1. Refactor: move `ide_assist::utils::suggest_name` to `ide-db::syntax_helpers::suggest_name` for reuse.
2. When completing `IdentPat`, detecte if the current node is a `let_stmt` or `fn_param`, and suggesting a new name based on the context.
fix: use Result type aliases in "Wrap return type in Result" assist
This commit makes the "Wrap return type in Result" assist prefer type aliases of standard library type when the are in scope, use at least one generic parameter, and have the name `Result`.
The last restriction was made in an attempt to avoid false assumptions about which type the user is referring to, but that might be overly strict. We could also do something like this, in order of priority:
* Use the alias named "Result".
* Use any alias if only a single one is in scope, otherwise:
* Use the standard library type.
This is easy to add if others feel differently that is appropriate, just let me know.

Apply size optimizations to panic machinery and some cold functions
* std dependencies gimli and addr2line are now built with opt-level=s
* various panic-related methods and `#[cold]` methods are now marked `#[optimize(size)]`
Panics should be cold enough that it doesn't make sense to optimize them for speed. The only tradeoff here is if someone does a lot of backtrace captures (without panics) and printing then the opt-level change might impact their perf.
Seems to be the first use of the optimize attribute. Tracking issue #54882

Rewrite lint_expectations in a single pass.
This PR aims at reducing the perf regression from https://github.com/rust-lang/rust/pull/120924#issuecomment-2202486203 with drive-by simplifications.
Basically, instead of using the lint level builder, which is slow, this PR splits `lint_expectations` logic in 2:
- listing the `LintExpectations` is done in `shallow_lint_levels_on`, on a per-owner basis;
- building the unstable->stable expectation id map is done by iterating on attributes.

internal: Lay basic ground work for standalone mbe tests
Most of our mbe hir-def tests don't actually do anything name res relevant, we can (and should) move those down the stack into `mbe/hir-expand`.
