clamd: Add devcontainers to project

ClamAV supports multiple platforms and sometimes requires the debugging of platform-specific bugs.

This commit adds one devcontainer for debian and another for AlmaLinux so that the codebase can be reopened inside of a devcontainer for debugging/testing purposes.

Jira: CLAM-2740
