[4.0] Remove Custom Locator Strategy from Playwright

[DavertMik]

Whatever Custom Locator Strategy is, it overblocats Playwright helper which is already really big

We should remove it as this code is AI slop and it is very badly written

@kobenguyent maybe you have any objections?
Can you assist?

The issue with Copilot PR that it has 0 idea of project structure and puts its code without looking into best architecture practices. Also Copilot is damn stupid copared to other AIs on market

@DavertMik no objections
