Add missing cstdint includes to avoid compiler errors because of unknown symbols uint32_t

[0xFEEDC0DE64]

I get a lot of compiler errors with a Catch2 project as uintXX_t is used everywhere but the required source file is not included. I fixed the few files that came up during my compilation process (under archlinux).

I guess in older versions of gcc and dependencies there was cstdint included somewhere else and only because of that Catch2 compiled so far.

One of my failed compilation processes looked like this:

Description

GitHub Issues

[horenmar]

I started reviewing the changes and wondered why the diff for catch_test_case_info.hpp doesn't make sense; in current devel, it already includes <cstdint>. Then I noticed that your branch is more than 200 commits behind devel -> could you update either to latest release, or to current devel and check whether the issue still reproduces?

Feel free to reopen the PR if you update your checkout and it doesn't fix the issue, but I am going to close this for now.
