Report trusted type violation during build and in editor

[jrieken]

Part of #103699 should be to make trusted types violations visible so that

• devs don't re-introduce violations that have been fixed already
• violations become visible and are fixed by devs themselves

One candidate would be the tsec-tool: https://github.com/googleinterns/tsec, e.g run it during builds and on dev-boxes

That sounds good! I am not sure tsec is good for that just yet, but we're currently improving the engine and its rules to have less false-negatives and false-positives. Adding @Siegrift and @uraj who are working on it.

We want to eventually integrate it into the vscode build toolchain to prevent regressions.

Closing since we have everything we need for this. The last and final step will be to cause build failures when TT violations are encountered
