Reduce release binary sizes (#65168)

Browse source 
Not sure how worth such optimization is WRT the speed, but for such
gains, seems worth opening to discuss?

-----------

Optimize selected workspace crates for size and hide Rust exports in
macOS bundles.

Measurements (release editor executable size):

| Platform | Architecture | Before (bytes) | After (bytes) | Reduction
(bytes / %) |
| --- | --- | ---: | ---: | ---: |
| macOS | ARM64 | 258,218,240 | 172,524,896 | 85,693,344 / 33.19% |
| Linux | x86_64 | 317,435,136 | 295,344,952 | 22,090,184 / 6.96% |
| Windows | x86_64 | 358,987,776 | 256,678,400 | 102,309,376 / 28.50% |
