NoArrayBufferZeroFillScope was added before the v8 option to create uninitialized backing stores was added. We can start moving away from it.

There are a handful of remaining instances in src/crypto that I remove in a separate PR. Once both of these land we can remove the NoArrayBufferZeroFillScope class entirely.

@nodejs/platform-smartos ... getting a flaky failure here: https://ci.nodejs.org/job/node-test-commit-smartos/58751/

@jasnell I think there might be some related failures. Specifically a test fails on ARM and Windows, with the same error:

https://ci.nodejs.org/job/node-test-binary-windows-js-suites/32184/RUN_SUBSET=2,nodes=win11-COMPILED_BY-vs2022/testReport/junit/(root)/parallel/test_fs_cp/

  AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
  + actual - expected

  + 'ERR_FS_EISDIR'
  - 'ERR_FS_CP_EINVAL'
            ^

      at file:///c:/workspace/node-test-binary-windows-js-suites/node/test/parallel/test-fs-cp.mjs:687:12

@nodejs/platform-smartos there seem to be some potential infra issue (or possibly it's a problem with this change) - tests are not actually run here.
