Auto merge of #66221 - ohadravid:doc-constants, r=Dylan-DPC
Show the actual value of constant values in the documentation Fixes #66099, making rustdoc show evaluated constant scalar values.  where `main.rs` is ``` pub const VAL3: i32 = i32::max_value(); pub const VAL4: i32 = i32::max_value() - 1; ``` As a fallback, when a constant value is not evaluated (either because of an error or because it isn't a scalar), the original expression is used for consistency. I mimicked the way min/max values of integers are [`pretty_print`ed](https://github.com/rust-lang/rust/blob/master/src/librustc/ty/print/pretty.rs#L900), to show both the value a the "hint". While a little goofy for `std`, in user crates I think it's actually rather helpful.
