[roll] Roll fuchsia [e1000] Migrate driver to netdev and DFv2

This change migrates the e1000 driver to use the network device FIDL
protocol instead of the ethernet banjo protocol. At the same time it
migrates the driver to use DFv2.

This is quite a significant alteration as it also changes the driver
from using internally allocated buffers one at a time. It now uses the
network device provided VMOs to transfers multiple buffers at the same
time.

This exposed some issues with the existing driver. At higher transfer
speeds the device would frequently lock up. This was solved by upreving
the core driver to the latest version. Additionally the existing driver
did not support link state change events, i.e. unplugging and replugging
the ethernet cable left the device in a disconnected state. Along with
the uprev the driver has been updated to properly support these link
state change events.

The third party code has been separated into its own source set so that
it can have its own set of compiler flags. This also allows the newly
introduced unit tests to stub out some of the third party code with a
fake implementation that allows the tests to run without having to
emulate hardware.

Tests: Manual testing, added unit tests
