feat: Lock orientation to portrait mode in YT Music.

[stelios1685]

Feature description

Introduce an in-app toggle that locks the YouTube Music app to portrait mode, independent of the device's system settings.
When enabled, this setting would force the app to remain in portrait orientation regardless of device rotation.

Thank you for considering this feature.

Motivation

Enhances usability by preventing unintended orientation changes.

The orientation can already be locked in landscape or portrait using the device settings.

Some manufacturers can also force an orientation on a per app basis.

Adding an in app button is redundant and more work than it's worth.

[LisoUseInAIKyrios]

A universal patch could force an orientation by modifying the app manifest and setting:

android:screenOrientation="portrait"
Or
android:screenOrientation="landscape"

But I'm unsure how useful that might be.
