Hook IDumpstateDevice 1.1 up to dumpstate binary.

Bug reports will now prefer v1.1 of the HAL since it supports
well-scoped modes that mirror BugreportManager. For new devices
launching with R, v1.1 must be supported if this (optional) HAL is
implemented. It's also fairly trivial to update existing devices to 1.1
if an OEM chooses.

As for what this means, bug reports will:
- Be smaller in many cases, and as a result, faster to collect
- Contain less unnecessary PII (e.g. camera logs should now be excluded
    for MODE_TELEPHONY)

There's still some minor cleanup to be done, but for now leaving TODOs.

Bug: 143183758
Bug: 143184495
Test: atest dumpstate_test
Test: take bug report on Cuttlefish and Blueline, check for v1.1 usage
