Move the show_usize marker function to a static
Currently, function items are always tagged unnamed_addr, which means that casting a function to a function pointer is not guaranteed to produce a deterministic address. However, once a function pointer is created, we do expect that to remain stable. So, this changes the show_usize function to a static containing a function pointer and uses that for comparisons. Notably, a *static* may have 'unstable' address, but the function pointer within it must be constant. Resolves issue 58320.
