Fix `items_after_test_module`: Ignore imported modules
Fixes#10713. It does a little bit of dark magic, but intention is what really counts.
changelog:[`items_after_test_module`]: Ignore imported modules (`mod foo;`) with no body.
Add configuration for `semicolon_block` lints
Does exactly what it says on the tin, suggests moving a block's final semicolon inside if it's multiline and outside if it's singleline.
I don't really like how this is implemented so I'm not too sure if this is ready yet. Alas, it might be ok.

Improve the help message + add a help span
This would close#10410, because it applies the general consensus achieved in that issue (that replacing `let _ = ...` to `_ = ...` doesn't present any benefits).
I also added a little help message span.

check for `..` pattern in `redundant_pattern_matching`
The `redundant_pattern_matching` lint currently checks for `if let Some(_) = ...`, but not for `if let Some(..) = ...`.
This PR makes sure to also check for the `..` pattern in tuple structs.
It also found one such instance in clippy itself so that shows it's worth checking for this pattern as well 😅

Fix false positive in `allow_attributes`
This would emit a warning if used in a proc-macro with the feature `lint_reasons` enabled. This is now fixed.
changelog: [`allow_attributes`]: Don't lint if in external macro
Ignore `shadow` warns in code from macro expansions
This PR fixes https://github.com/rust-lang/rust-clippy/issues/9757
I am in doubt if just looking for `pat.span.from_expansion()` would be sufficient instead of looking for both `pat.span.desugaring_kind().is_some()` or `pat.span.from_expansion()`. The tests (including the new one) passes if I leave the only `if pat.span.from_expansion()`. Any feedbacks?
Also, this is my first PR here, sorry for anything and thanks for the patience!

New lint: detect `if` expressions with simple boolean assignments to the same target
Closes#10430
changelog: [`needless_bool_assign`] new lint to detect simple boolean assignment to the same target in `if` branches
use `is_inside_const_context` for `in_constant` util fn
Fixes#10452.
This PR improves the `in_constant` util function to detect more cases of const contexts. Previously this function would not detect cases like expressions in array length position or expression in an inline const block `const { .. }`.
changelog: [`bool_to_int_with_if`]: recognize array length operand as being in a const context and don't suggest `usize::from` there
Don't suggest `suboptimal_flops` unavailable in nostd
Fixes#10634
changelog: Enhancement: [`suboptimal_flops`]: Do not suggest `{f32,f64}::abs()` or `{f32,f64}::mul_add()` in a `no_std`-environment.
Add `items_after_test_module` lint
Resolves task *3* of #10506, alongside *1* resolved at #10543 in an effort to help standarize a little bit more testing modules.

make [`len_zero`] lint not spanning over parenthesis
