Request location permissions for BLE scan on Android 12 and older

[twyatt]

Attempted to use moko-permissions on an Android 11 device (Pixel 2 XL) and found that after granting permissions, scanning would silently not deliver any advertisements. Determined that the problem was missing location permission.

Per Bluetooth permissions documentation, the following permissions are needed for Bluetooth Low Energy scanning (summarized in table form for readability):

Version	SDK / API level	Version code	Permission required
Android 15	Level 35	VANILLA_ICE_CREAM	BLUETOOTH_SCAN
Android 14	Level 34	UPSIDE_DOWN_CAKE	BLUETOOTH_SCAN
Android 13	Level 33	TIRAMISU	BLUETOOTH_SCAN
Android 12	Level 32	S_V2	BLUETOOTH_SCAN
Android 12	Level 31	S	BLUETOOTH_SCAN
Android 11	Level 30	R	ACCESS_FINE_LOCATION
Android 10	Level 29	Q	ACCESS_FINE_LOCATION
Android 9	Level 28	P	ACCESS_COARSE_LOCATION
Android 8	Level 27	O_MR1	ACCESS_COARSE_LOCATION
Android 8	Level 26	O	ACCESS_COARSE_LOCATION
Android 7	Level 25	N_MR1	ACCESS_COARSE_LOCATION
Android 7	Level 24	N	ACCESS_COARSE_LOCATION
Android 6	Level 23	M	ACCESS_COARSE_LOCATION
Android 5	Level 22	LOLLIPOP_MR1	ACCESS_COARSE_LOCATION
Android 5	Level 21	LOLLIPOP, L	ACCESS_COARSE_LOCATION

Tested these changes as working on:

Phone	Android version	Permission requirement
Google Pixel 5	Android 14	BLUETOOTH_SCAN
Google Pixel 2 XL	Android 11	ACCESS_FINE_LOCATION
Samsung Galaxy J5	Android 5.1.1	ACCESS_COARSE_LOCATION

I have not tested permission for BLE connect yet, expect an additional PR if changes are needed there as well.

Tested the BLUETOOTH_CONNECT and found that no changes are needed in moko permissions.

Tested with:

Phone	Android version	Permission requirement
Google Pixel 5	Android 14	If BLUETOOTH_SCAN is granted, will connect w/o requesting BLUETOOTH_CONNECT If BLUETOOTH_SCAN is not requested prior, BLUETOOTH_CONNECT is needed to connect
Google Pixel 2 XL	Android 11	None (connects w/o requesting BLUETOOTH_CONNECT; if requested, BLUETOOTH_CONNECT is granted immediately w/o showing dialog)
Samsung Galaxy J5	Android 5.1.1	None (connects w/o requesting BLUETOOTH_CONNECT; if requested, BLUETOOTH_CONNECT is granted immediately w/o showing dialog)

Note

All devices tested immediately grant permission (without showing dialog) when requesting BLUETOOTH_CONNECT if BLUETOOTH_SCAN was already granted.
