Replace .map_or(false, $closure) with .is_some_and(closure) (#6244)

**Summary**
[Option::is_some_and](https://doc.rust-lang.org/stable/std/option/enum.Option.html#method.is_some_and)
and
[Result::is_ok_and](https://doc.rust-lang.org/std/result/enum.Result.html#method.is_ok_and)
are new methods is rust 1.70. I find them way more readable than
`.map_or(false, ...)`.

The changes are `s/.map_or(false,/.is_some_and(/g`, then manually
switching to `is_ok_and` where the value is a Result rather than an
Option.

**Test Plan** n/a^
