fix(electron): browser window ids out of sync

[samuelmaddock]

fixes #6760
fixes #6748

Playwright's Electron implementation is keeping track of BrowserWindow IDs itself which has issues that cause it to go out of sync. This has been a blocker for complex Electron apps using multiple windows or BrowserViews.

I've introduced a new API to Electron which will allow using the DevTools Target ID as a stable lookup identifier for WebContents: electron/electron#29399

This PR is set as a draft to receive feedback and wait for Electron changes to be merged and released:

• v12 backport feat: add webContents.fromDevToolsTargetId() electron/electron#30730
• v13 backport feat: add webContents.fromDevToolsTargetId() electron/electron#30731
• v14 backport feat: add webContents.fromDevToolsTargetId() electron/electron#30732
• v15 backport feat: add webContents.fromDevToolsTargetId() electron/electron#30733

v12.2.0 has been released now with these changes. This PR upgrade to it since it's the minimum supported version.

TS error after upgrading Electron:

Found 1 error.

It seems like @types/node needs to be updated. After bumping it to ^12.12.6, I receive 57 errors. What's the preferred path forward in this case? New PR to update @types/node?

@samuelmaddock we can split it in two. I'll take care that #8837 lands soon which does exactly that, then your PR should pass.

[pavelfeldman]

I landed the roll, you can rebase this PR and we will merge.

For the record: After this patch the minimum required versions of Electron are:

• v12.2.0+
• v13.4.0+
• v14.0.0+
• v15.0.0+
