This is a follow-up ticket to BF-40058.

BF-40058 is likely a collection of failures caused by memory corruption, possibly due to a use-after-free error.

To improve diagnostics, whenever an illegal value is detected in a memory region (e.g. page type, cell type, etc.), we should dump the entire memory region along with the value's offset and size within that region (for example, the entire page).
This will help us identify the nature and source of the corruption more effectively.

Add a new function: __wt_illegal_value_in_block(session, v, mem, size, offset) and replace calls to __wt_illegal_value(session, v) where applicable.
