This comes up during review, so instead of wasting review cycles on this, just enforce it via CI

utACK fa451d4

I verified that all the removed const qualifiers were top-level, and as such can be safely removed. Checking this with clang-tidy makes the review process more efficient.

ACK fa451d4.

Maybe add a commit to address #26705 (comment) as well?

A note: it looks not related to the readability-const-return-type check, but it does a few lines below in ConsumeIntegralInRange<decltype(sz)>(0, sz - 1).

Correct, decltype(sz) is const ..., which will be the return value of ConsumeIntegralInRange, and thus cause the readability-const-return-type fail
