[dice] Remove unused service android.hardware.security.dice 

This cl removes the unused service android.hardware.security.dice
together with all its usages (all of them are tests), because the
service is incomplete and not used anywhere for now and in the
near future.

The cl also removes dice from the compat matrix.

This helps us reduce some maintainance burden for the Rust dice
wrapper libraries such as libdiced_open_dice[_nostd],
libdiced_sample_inputs, libdiced_utils and their tests.

Test: atest diced_utils_test diced_sample_inputs_test \
diced_open_dice_cbor_test \
libdiced_open_dice_nostd.integration_test \
libdiced_open_dice.integration_test diced_open_dice_cbor_test
Test: m pvmfw_img microdroid_manager

///////////////////////////////////////////////////////////////////////////////



// This file is a snapshot of an AIDL file. Do not edit it manually. There are

// two cases:

// 1). this is a frozen version file - do not edit this in any case.

// 2). this is a 'current' file. If you make a backwards compatible change to

//     the interface (from the latest frozen version), the build system will

//     prompt you to update this file with `m <name>-update-api`.

//

// You must not make a backward incompatible change to any AIDL file built

// with the aidl_interface module type with versions property set. The module

// type is used to build AIDL files in a way that they can be used across

// independently updatable components of the system. If a device is shipped

// with such a backward incompatible change, it has a high risk of breaking

// later when a module using the interface is updated, e.g., Mainline modules.
