Auto merge of #9688 - Alexendoo:msrv-tests, r=Manishearth

Move MSRV tests into the lint specific test files

There are currently two ways MSRV tests are done in the ui test suite, adding a case to the `#![clippy::msrv = "1.0"]` `tests/ui/min_rust_version_attr.rs` or adding the two `msrv_1_xx` functions to the test file of the lint in question

This updates the clippy book to suggest the `msrv_1_xx` style, and replaces the tests in `tests/ui/min_rust_version_attr.rs` with ones of that style

Almost the entire diff is just moving stuff around as a result, I made sure to check the line numbers the lints are emitted at correspond with the right `msrv` case, so feel free to only skim that part

Once the `msrv` is added to the lint, a relevant test case should be added to
`tests/ui/min_rust_version_attr.rs` which verifies that the lint isn't emitted
if the project's MSRV is lower.
the lint's test file, `tests/ui/manual_strip.rs` in this example. It should
have a case for the version below the MSRV and one with the same contents but
for the MSRV version itself.
```rust
#![feature(custom_inner_attributes)]
...
fn msrv_1_44() {
#![clippy::msrv = "1.44"]
/* something that would trigger the lint */
}
fn msrv_1_45() {
#![clippy::msrv = "1.45"]
/* something that would trigger the lint */
}
```
As a last step, the lint should be added to the lint documentation. This is done
in `clippy_lints/src/utils/conf.rs`:
