bootstrap/devcontainer: Install required packages for wpt. (#44109)

Based on our linux-wpt.yml workflow update our bootstrap and
devcontainer package list.
This should make the local environment closer to our CI environment when
running WPT. We only purge the droid font in the devcontainer, since we
shouldn't purge packages for the user.


mesa-vulkan-drivers was added in
71e0372ac1, so it's probably required for
WebGPU.
fonts-noto-cjk was added in 2b0d2ecc73.

In both cases no reason was given why it can't be in bootstrap, so
presumably its just an oversight.

Testing: bootstrap is ran in CI, and the packages were already being
installed by the wpt workflow.
