REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4115

Adds initial support for enabling CodeQL Code Scanning in this
repository per the RFC:

  https://github.com/tianocore/edk2/discussions/3258

Adds the following new files:
  - .github/workflows/codql-analysis.yml - The main GitHub workflow
    file used to setup CodeQL in the repo.
  - .github/codeql/codeql-config.yml - The main CodeQL configuration
    file used to customize the queries and other resources the repo
    is using for CodeQL.
  - edk2.qls - A query set of queries to run for CodeQL.
