fix: consider all tokens in macro expr when analyzing locals
Fixes#14687
2 fixes for `extract_function` assist (related closely enough that I squashed into one commit):
- Locals in macro expressions have been analyzed only when they are in the top-level token tree the macro call wraps. We should consider all descendant tokens.
- `self` in macro expressions haven't been analyzed.
Fix `preorder_expr` skipping the `else` block of let-else statements
Fixes exit/yield points not getting highlighted in such blocks for `highlight_related` (#14813; and possibly other bugs in features that use `preorder_expr`).

MIR episode 5
This PR inits drop support (it is very broken at this stage, some things are dropped multiple time, drop scopes are wrong, ...) and adds stdout support (`println!` doesn't work since its expansion is dummy, but `stdout().write(b"hello world\n")` works if you use `RA_SYSROOT_HACK`) for interpreting. There is no useful unit test that it can interpret yet, but it is a good sign that it didn't hit a major road block yet.
In MIR lowering, it adds support for slice pattern and anonymous const blocks, and some fixes so that we can evaluate `SmolStr::new_inline` in const eval. With these changes, 57 failed mir body remains.
fix: Diagnose non-value return and break type mismatches
Could definitely deserve more polished diagnostics, but this at least brings the message across for now.
fix: place type inlay hints after the item and without left-padding

fix(analysis-stats): divided by zero error
## What does this PR try to resolve?
2023-05-15 rust-analyzer suffers from
```
thread 'main' panicked at 'attempt to divide by zero', crates/rust-analyzer/src/cli/analysis_stats.rs:230:56
```
This commit <51e8b8ff14> might be the culprit.
This PR uses `percentage` function to avoid the classic “division by zero” bug.
## Reproducer
```console
cargo new ra-test
pushd ra-test
echo "pub type Foo = u32;" >> src/lib.rs
rust-analyzer analysis-stats .
```
