`--enable-cache` path print not respected by `translate-c`

Zig Version

0.11.0-dev.2157+f56f3c582

Steps to Reproduce and Observed Behavior

(For context, ran into this @ zigtools/zls#1080)

1. Create a slay.h file
2. zig translate-c slay.h --enable-cache
3. Observe that --enable-cache's promise about "print[ing] path to stdout" is not respected

Expected Behavior

translate-c output should be written to cache and the path to that cache location printed to stdout.

Culprit is 8b2d872; this seems rather intentional so I'll leave this for someone with more knowledge on this intricate web of caching :P

On first sight, the simplest solution seems to be to correct the help output regarding --enable-cache and add another parameter, something like --print-cache-path that prints the cache path instead of the contents of the cached output file.
