RFR: 8346990: Remove INTX_FORMAT and UINTX_FORMAT macros [v2]

[Coleen Phillimore]

> There are a lot of format modifiers that are noisy and unnecessary in the code.  This change removes the INTX variants.  It's not that disruptive even for backporting because %z modifier has been available for a long time so should backport fine.  This was mostly done with a sed script plus some hand fixups.
> 
> Testing mach5 and other platform cross compilations in progress.  Opening this for GHA testing.
