feat(Android): update SwitchCompat to MaterialSwitch

[adrcotfas]

Summary:

The Android Switch has been using SwitchCompat, a Material Design 2 component from 2018 that produces a visually outdated toggle. This PR migrates it to Material Design 3's MaterialSwitch. A ContextThemeWrapper ensures correct MD3 rendering regardless of the host app's theme.
New Android-only props, consistent with the existing trackColor: {false, true} pattern:

• thumbColorForTrue / thumbColorForFalse: per-state thumb color (thumbColor remains as an alias for seamless migration)
• thumbIcon: {false?: string, true?: string}: per-state drawable resource shown inside the thumb
• thumbIconTint: color tint for the thumb icon

Unspecified states fall back to Material theme attributes (colorPrimary, colorSurfaceContainerHighest, colorOnPrimary, colorOutline).

Changelog:

[ANDROID] [CHANGED] - Migrate Switch from the outdated MD2 SwitchCompat to MaterialSwitch (MD3)
[ANDROID] [ADDED] - Add thumbColorForTrue, thumbColorForFalse, and thumbIcon: {false?: string, true?: string} props to Switch for per-state thumb color and icon control on Android

Test Plan:

Tested on Android via rn-tester Switch examples:

• All existing examples (on/off, disabled, custom colors, events) work without regressions
• New MD3 example shows single-state (thumbIcon={{true: 'ic_check'}}) and dual-state (thumbIcon={{false: 'ic_close', true: 'ic_check'}}) icon usage
• Android-only props are silently ignored on iOS
