WL#12619: Deprecate (5.7) and remove (8.0) resolve_stack_dump

Deprecate resolve_stack_dump in 5.7 and remove it in 8.0.

resolve_stack_dump resolves a numeric stack dump to symbols, cf.

https://dev.mysql.com/doc/refman/8.0/en/resolve-stack-dump.html

It no longer serves any useful purpose (all stack dumps from the normal server
builds are symbolized these days).

Feedback from Support indicates that resolve_stack_dump is no longer relevant
(addr2line is used).
