chore: Drop OpenCL, and refactor Cargo.toml for workspace use (#1046)

* chore: Drop OpenCL, and refactor Cargo.toml for workspace use

- Refined GitHub GPU CI workflow by removing OpenCL Rust tests and enabling only CUDA tests
- Revamped package settings to workspace level across the GitHub repository, implemented in `lurk-macros`, `lurk-metrics` and `Cargo.toml`
- Removed specific dependencies `pasta-msm` and `grumpkin-msm` from `Cargo.toml`,
- Reordered the features in `Cargo.toml`, removed `opencl` and some deps off `portable` for better maintainability
- Cleaned up minor formatting issue in 'lurk-macros/src/lib.rs'

* chore: bump rust msrv & allow CI to find it
