Backport 1/1 commits from #118760 on behalf of @xinhaoz.

…ent_bundle

Previously only those with the VIEWACTIVITY role could use the crdb_internal.request_statement_bundle builtin. We should allow the VIEWACTIVITY privilege as well since role options are now deprecated. This allow also allow stmt bundle requests to be made from db-console for users with this granted privilege.

Epic: none
Fixes: #118759

Release note (bug fix): Those with VIEWACTIVITY privilege can now request statement bundles using crdb_internal.requets_statement_bundle or via db-console's sql activity page.

Release justification: bug fix - use privilege instead of deprecated role

Thanks for opening a backport.

Please check the backport criteria before merging:

• Backports should only be created for serious
  issues or test-only changes.
• Backports should not break backwards-compatibility.
• Backports should change as little code as possible.
• Backports should not change on-disk formats or node communication protocols.
• Backports should not add new functionality (except as defined
  here).
• Backports must not add, edit, or otherwise modify cluster versions; or add version gates.
• All backports must be reviewed by the owning areas TL and one additional
  TL. For more information as to how that review should be conducted, please consult the backport
  policy.

If your backport adds new functionality, please ensure that the following additional criteria are satisfied:

• There is a high priority need for the functionality that cannot wait until the next release and is difficult to address in another way.
• The new functionality is additive-only and only runs for clusters which have specifically “opted in” to it (e.g. by a cluster setting).
• New code is protected by a conditional check that is trivial to verify and ensures that it only runs for opt-in clusters. State changes must be further protected such that nodes running old binaries will not be negatively impacted by the new state (with a mixed version test added).
• The PM and TL on the team that owns the changed code have signed off that the change obeys the above rules.
• Your backport must be accompanied by a post to the appropriate Slack
  channel (#db-backports-point-releases or #db-backports-XX-X-release) for awareness and discussion.

Also, please add a brief release justification to the body of your PR to justify this
backport.

can you just move the import back to where it should be? (and check your editor's linter settings 😇)
