test: Remove gccbug_90348 test case

The test case no longer detects this specific issue for GCC versions
12.1+, as explained in the
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90348 thread and in this
compiler-explorer playground:
https://godbolt.org/z/Y48osrjM8

So remove the test case and update the -fstack-reuse=none cmake
docstring with the underlying affected GCC versions, and the bug URL.

The short version

What changed, and why it matters

This commit removes an old automated test that checked whether the GCC compiler had a specific bug. The test no longer catches the bug in newer GCC versions, so the developers deleted it and updated a build-system comment to note which GCC versions are affected. There is no change to the actual Bitcoin Core program code or its security behavior.

Recommended action

No security action required. This is a routine test-maintenance commit. Continue using the existing -fstack-reuse=none workaround for affected GCC builds.

Security signals we found

01

No functional code changes

02

Only test code and build comments removed/updated

03

Existing compiler mitigation (-fstack-reuse=none) remains enabled
