[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
