tools: cache V8 build on test-shared workflow
This commit makes the CI use the Nix/Cachix cache rather than the sccache one for building V8 and its dependencies. This should speed up the average test-shared build time and reduce the stress on the GHA binary cache – at the expense of slower builds when touching a file used to building V8.
