PhoneCapabilities changes for device capabilities

Change PhoneCapability structure to contain static capabilities for:
* the entire device
* each modem/radio
* each SIM slot

Created SimSlotCapability and SlotType to hold information about
device SIM slot capabilities (separate from SimSlotStatus).

Created ModemFeatures to express modem capabilities as a bitfield
of concurrently supportable modem features.

PhoneCapability has fields for UE categories, bands, access networks,
and modem switching linger time. It also contains a lists of logical
modem UUIDs, SIM slot capabilities, and all possible concurrently
supportable modem features.

TelephonyManager will have an API that returns
* the PhoneCapability for the device
* active set of ModemFeatures

Apps with CARRIER_PRIVILEGE can use these APIs to access all
capabilities of a device (eg. 5G capable, DSDS capable, etc.) and
use them to make decisions based on what the device can support.
