Add toggle to hide the status bar mute icon on Android 17 QPR1+

[mbahakeskin]

Android 17 QPR1 moved status bar icon rendering to a new Compose-based pipeline (behind the status_bar_root_modernization and status_bar_system_status_icons_in_compose aconfig flags, both enabled and read-only on release builds). The old icon_blacklist Secure setting that StatusbarMisc previously relied on for hiding things like the mute icon is no longer read by this new pipeline.

I found that the new code (HomeStatusBarIconBlockListInteractor) reads a separate, dedicated Secure setting for the mute icon: status_bar_show_mute_icon (0 hides it, default is shown). SystemUI observes this reactively, so writing it takes effect immediately, no restart needed.

This adds a "Hide Mute Icon" switch under Statusbar > Icon Visibility. It writes status_bar_show_mute_icon from inside the SystemUI hook (mContext there is SystemUI's own context, which already holds WRITE_SECURE_SETTINGS), the same approach StatusbarMisc already uses for the lockscreen carrier/statusbar hiding.

I don't see an equivalent setting for Bluetooth yet on QPR1. QPR2 Beta 4 adds a new BluetoothIconViewModel, but its visibility is computed purely from Bluetooth connection state, no settings-backed toggle. Might be worth revisiting once that lands in a stable release.

Compiled clean (compileFossDebugKotlin), but I don't have an LSPosed test rig handy, so this hasn't been verified on-device. Happy to adjust if something's off.

Thanks for the PR. I think we should gate this setting behind an Android 17 check so that it isn't shown to Android 16 users.
