Update to OpenSSL 3. (#5174)

[SC-36844](https://app.shortcut.com/tiledb-inc/story/36844/update-to-openssl-3)

This PR removes the `openssl` vcpkg port overlay, which unpins OpenSSL
from version 1.1.1.t to whichever is set in the vcpkg `builtin-baseline`
(currently version 3.1.4).

Validated by successfully building the Core on WSL. No warnings or
errors about deprecated APIs were emitted by the compiler, which means
that this PR does not have to touch any first-party code.

---
TYPE: IMPROVEMENT
DESC: The version of OpenSSL linked to the release artifacts was updated
to 3.1.4, and moving forward will be synced to the vcpkg
`builtin-baseline`.
