cmake: allow `CURL_LTO` regardless of `CURL_BUILD_TYPE`, enable in CI

Before this patch `CURL_LTO` only applied to builds explicitly
configured for `Release` or `RelWithDebInfo` via `CURL_BUILD_TYPE`.

After this patch it enables LTO regardess of build type.

Also:
- GHA/linux: enable LTO in an existing job.

Follow-up to 4ccf7622db04af58442c460b8091b952585de5c7 #4799
Closes #15829
