Add support for writeBlocking 

Adds support for the Sensors HAL to use writeBlocking when sending
sensor events to the framework.

Bug: 111070257
Test: Builds, verified that if the default implementation is modified
      to use a writeBlocking call, the framework receives events, and
      the HAL blocks if the Event FMQ is full.
