Material 3 bar code & QR code scanners

[nbradbury]

Fixes #21329

This PR converts the QR code & bar code scanners to Material3. To test:

• Sign into the app with an account that doesn't have 2FA enabled (QR login isn't supported when 2FA is enabled)
• Me > Scan Login Code
• On your desktop/laptop, visit https://wordpress.com/log-in
• Choose "Login via App"
• Verify the various screens appear correctly

@nbradbury when I tap Scan Login Code I see a full-screen camera view with no other UI besides the default Android bottom bar (overview, home, back buttons). Is that the expected appearance?

Also, when I attempt to scan the QR code, the app does not acknowledge its presence or proceed with authentication in the web browser—i.e., it appears to be broken. I am using a non-2FA account. Is the flow succeeding for you?

I tested using a Samsung Galaxy S20 running Android 13.

I don't have much insight into this feature, but this is how it works in trunk.

If I use the app to scan the code from my laptop, it does then proceed to login on the laptop. Regardless, it's a weird experience, and I'm doubtful of its usefulness.

@dcalhoun Thanks for the review! I agree with you about the problems with this feature and have opened this issue.
