During our transition to v5 toolchain, it is discovered that some of our switch cases does not have a default statement thus producing warnings like:

/data/mci/c42db90c3cc587595fc36b0d48cfef5d/wiredtiger/src/include/cell_inline.h:594:5: warning: 'switch' missing 'default' label [-Wswitch-default]
594 |     switch (WT_CELL_SHORT_TYPE(cell->__chunk[0])) {
    |     ^ 

We are adding an ignore flag for this warning in  WT-14121. However, in the long term, we want to ensure that our switch cases include default statements.

The goal of this ticket is to compile WiredTiger without the -Wswitch-default ignore flag and resolve any warnings related to missing default cases in switch statements.
