Replace Azure blob vcpkg caching with run-vcpkg action

[Copilot]

Replace manual Azure blob storage caching for vcpkg with the official lukka/run-vcpkg@v11 action, which provides automatic binary caching through GitHub Actions cache.

Changes

ResInsightWithCache.yml

• Replace manual bootstrap-vcpkg step with lukka/run-vcpkg@v11 action
• Remove Azure secret validation and VCPKG_BINARY_SOURCES environment variables
• Remove unused vcpkg-bootstrap entries from matrix configuration

clang-tidy.yml

• Replace manual bootstrap-vcpkg step with lukka/run-vcpkg@v11 action
• Remove global and step-level VCPKG_BINARY_SOURCES environment variables

The action configuration points to the existing vcpkg submodule:

- name: Setup vcpkg
  uses: lukka/run-vcpkg@v11
  with:
    vcpkgDirectory: '${{ github.workspace }}/ThirdParty/vcpkg'

Binary caching is handled automatically by the action via GitHub Actions cache backend, leveraging the existing vcpkg.json and vcpkg-configuration.json manifest files.
