Add --clobber-cache option to initdb, for CCA testing. Commit 4656e3d66 replaced the "#define CLOBBER_CACHE_ALWAYS" testing mechanism with a GUC, which has been a great help for doing cache-clobber testing in more efficient ways; but there is a gap in the implementation. The only way to do cache-clobber testing during an initdb run is to use the old method with #define, because one can't set the GUC from outside. Improve this by adding a switch to initdb for the purpose.
(Perhaps someday we should let initdb pass through arbitrary "-c NAME=VALUE" switches. Quoting difficulties dissuaded me from attempting that right now, though.) Back-patch to v14 where 4656e3d66 came in.
