[SRU][N:aws/Q:aws/R:aws][PATCH v2 1/1] Enable ENA_ETHERNET as built-in to avoid race

[Leah Goldberg]

BugLink: https://bugs.launchpad.net/bugs/2144694

Currently, cloud-init may fail to detect the EC2 datasource during
the local init stage if the kernel hasn’t initialized the NIC in time.
This can prevent metadata fetching and block SSH on first boot. Making
ENA_ETHERNET built-in allows instances to boot reliably. We can revisit
making ENA modular once the underlying cloud-init race is resolved.

Added CONFIG_ENA_ETHERNET is `y` in debian.aws/config/annotations.
