Rollup merge of #109665 - fee1-dead-contrib:rm-remap-queries, r=oli-obk 
Remove `remap_env_constness` in queries

This removes some of the complexities with const traits. #88119 used to be caused by this but was fixed by `param_env = param_env.without_const()`.

Deadbeef b17e6680d6 Move const trait bounds checks to MIR constck 
Fixes #109543. When checking paths in HIR typeck, we don't want to check
for const predicates since all we want might just be a function pointer.
Therefore we move this to MIR constck and check that bounds are met
during MIR constck.

Rollup merge of #106541 - fee1-dead-contrib:no-const-check-no, r=thomcc 
implement const iterator using `rustc_do_not_const_check`

Previous experiment: #102225.

Explanation: rather than making all default methods work under `const` all at once, this uses `rustc_do_not_const_check` as a workaround to "trick" the compiler to not run any checks on those other default methods. Any const implementations are only required to implement the `next` method. Any actual calls to the trait methods other than `next` will either error in compile time (at CTFE runs), or run the methods correctly if they do not have any non-const operations. This is extremely easy to maintain, remove, or improve.
