[camera_android_camerax] Remove logic used to previously correct preview rotation

[camsim99]

Removes correction logic used to the correct the rotation of the camera preview, since it appears* to not be needed anymore.

Partially addresses flutter/flutter#154241.

*This is not true for emulators, but if we are ok landing this issue for real devices, I'll file an issue for emulators and follow up there. jonahwilliams@ mentioned there is known different behavior in emulators with Impeller, so this fact is not totally a surprise.

My basis for landing this is:

1. I tested the following devices that use both Impeller backends and this PR works:

• Realme X2 Pro, Android 11 (API 30) that uses Vulkan
• Pixel 3A, Android 12 (Android 31/32) that falls back to OpenGLES
• Samsung Galaxy (Android 8.1.0) that uses OpenGLES

2. If this misses an edge case (like a class of device), this PR will make it easier to debug what is going on, since the camera preview will now only introduce a rotation if the device itself is rotated (as per the logic in

   packages/packages/camera/camera/lib/src/camera_preview.dart

   Lines 46 to 72 in 8ca81bd

   	Widget _wrapInRotatedBox({required Widget child}) {
   	if (kIsWeb || defaultTargetPlatform != TargetPlatform.android) {
   	return child;
   	}
   	return RotatedBox(
   	quarterTurns: _getQuarterTurns(),
   	child: child,
   	);
   	}
   	bool _isLandscape() {
   	return <DeviceOrientation>[
   	DeviceOrientation.landscapeLeft,
   	DeviceOrientation.landscapeRight
   	].contains(_getApplicableOrientation());
   	}
   	int _getQuarterTurns() {
   	final Map<DeviceOrientation, int> turns = <DeviceOrientation, int>{
   	DeviceOrientation.portraitUp: 0,
   	DeviceOrientation.landscapeRight: 1,
   	DeviceOrientation.portraitDown: 2,
   	DeviceOrientation.landscapeLeft: 3,
   	};
   	return turns[_getApplicableOrientation()]!;
   	}

   ) with no additional logic concerning the sensor orientation and UI orientation as it does now.

Works for me as of today on the following devices I tested (and their Impeller logs):

• Pixel 3A, Android 12 (Android 31/32)
  I/flutter (13294): [INFO:flutter/shell/platform/android/android_context_vk_impeller.cc(64)] Known bad Vulkan driver encountered, falling back to OpenGLES.
  I/flutter (13294): [IMPORTANT:flutter/shell/platform/android/android_context_gl_impeller.cc(94)] Using the Impeller rendering backend (OpenGLES).
• Realme X2 Pro, Android 11 (API 30)
  I/flutter (10164): [IMPORTANT:flutter/shell/platform/android/android_context_vk_impeller.cc(60)] Using the Impeller rendering backend (Vulkan).
  Vulkan
• Samsung Galaxy (Android 8.1.0)
  I/flutter (11694): [IMPORTANT:flutter/shell/platform/android/android_context_gl_impeller.cc(94)] Using the Impeller rendering backend (OpenGLES).

I fear this broke the live camera preview on some Android devices (where the preview is now distorted and rotated by 90°). For example see: khoren93/flutter_zxing#169

Preview rotation correction logic was added back in camera_android_camerax: 0.6.14; please try it out!

Works like a charm. Thanks
