Permissions.CheckStatusAsync<Permissions.Bluetooth> on iOS returns Granted when don't allow is chosen

[ckrutsinger]

Description

status = await Permissions.CheckStatusAsync<Permissions.Bluetooth>();
is returning PermissionStatus.Granted even though I choose Not Allowed.

Steps to Reproduce

iOS ONLY

1. Include this in Info.plist:

	<key>NSBluetoothAlwaysUsageDescription</key>
	<string>app collects location data to enable vehicle services including current location and event location</string>

2. Upon app install, you should be prompted for Bluetooth permission, choose "Don't Allow". If not prompted, use Settings app to disallow Bluetooth for app
3. After app launches, call await Permissions.CheckStatusAsync<Permissions.Bluetooth>() and response will be PermissionStatus.Granted instead of PermissionStatus.Denied Demo app will put the permission status into the click me button upon being clicked

@ckrutsinger You could try if you also get the issue with the latest MAUI version of 8.0.21: #22059

Today I tried on 8.0.21 and 8.0.14. Both still exhibit returning Granted even if Don't Allow is chosen at install. I wonder if the issue has anything to do with the presence of both permission tags in Info.plist:

	<key>NSBluetoothPeripheralUsageDescription</key>
        ...
	<key>NSBluetoothAlwaysUsageDescription</key>

On first launch after install, the app prompts with the string for Always usage. There is no prompt for the now deprecated Peripheral usage permission. So it is the Always usage I am not allowing. Is the permission check returning the Peripheral permission, which apparently doesn't require explicit authorization? await Permissions.CheckStatusAsync<Permissions.Bluetooth>(); doesn't have an option to inquire about the Always permission.

I have added a demo project which replicates the bug on latest MAUI version. See MainPage.xaml.cs

Verified this issue with Visual Studio 17.10 Preview 5 (8.0.21&8.0.7). Can repro on iOS platform with sample project.
