f4b1ad43d4 gdb: protect debug::the_database from lto
Clang 18.1 with lto gained the ability to eliminate dead stores.
Since debug::the_database is write-only as far as the compiler understands
(it is read only by gdb), all writes to it are eliminated.

Protect writes to the variable by marking it volatile.

c65692a13a test: extract debug::the_database out
we want to integrate some perf test into scylla executable, so we
can run them on a regular basis. but `test/lib/cql_test_env.cc`
shares `debug::the_database` with `main.cc`, so we cannot just
compile them into a single binary without changing them.

before this change, both `test/lib/cql_test_env.cc`
and `main.cc` define `debug::the_database`.

after this change, `debug::the_database` is extracted into
`debug.cc`, so it compiles into a separate compiling unit.
and scylla and tests using seastar testing framework are linked
against `debug.cc` via `scylla_core` respectively. this paves the road to
integrating scylla with the tests linking aginst
`test/lib/cql_test_env.cc`.
