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
sorry it should be a quick fix but I was caught up by other stuffs last couple weeks 🤦♂️

Suppress the triggering of some lints in derived structures
Fixes#10185Fixes#10417
For `integer_arithmetic`, `arithmetic_side_effects` and `shadow_reuse`.

Add size-parameter to unecessary_box_returns
Fixes#10641
This adds a configuration-knob to the `unecessary_box_returns`-lint which allows _not_ linting a `fn() -> Box<T>` if `T` is "large". The default byte size above which we no longer lint is 128 bytes (due to https://github.com/rust-lang/rust-clippy/issues/4652#issue-505670554, also used in #9373). The overall rational is given in #10641.

changelog: Enhancement: [`unnecessary_box_returns`]: Added new lint configuration `unnecessary-box-size` to set the maximum size of `T` in `Box<T>` to be linted

resolve: Pre-compute non-reexport module children
Instead of repeating the same logic by walking HIR during metadata encoding.
The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list. They can be encoded separately if this need ever arises.
`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Clear with drain
Fixes#10572: both the original intent of the issue (extending `clear_with_drain`) and the false negative for `collection_is_never_read` I found in the process are fixed by this PR.
changelog: [`clear_with_drain`]: extend to 5 other types of containers. [`collection_is_never_read`]: fix false negative for `String`s.
