Disable breakpoint hint when a test loading icon is present

[joyceerhl]

Fixes #180880

vscode/src/vs/platform/theme/common/iconRegistry.ts

Line 332 in ab7c32a

export const spinningLoading = ThemeIcon.modify(Codicon.loading, 'spin');

The loading codicon is used for one of the testing states:

vscode/src/vs/workbench/contrib/testing/browser/icons.ts

Line 40 in ab7c32a

[TestResultState.Running, spinningLoading],

I haven't seen this with the VS Code selfhost test provider but it appears to show up for Pytest.
