Multi-stage Docker builds (#2850)

This builds on @S7evinK's work to make multi-stage Docker builds. Now
that we can build SQLite without Cgo this should be much simpler and
should make Docker builds in CI significantly faster.

## Dockerfiles
The `Dockerfile` builds the base image which contains all of the Dendrite
components. The `Dockerfile.component` file takes the given component, as
specified with `--buildarg component=` from the base image and produce
smaller component-specific images, which are substantially smaller and do
not contain the Go toolchain etc.
The `Dockerfile` is a multistage file which can build all four Dendrite
images depending on the supplied `--target`. From the root of the Dendrite
repository, run:
```
docker build . --target monolith -t matrixdotorg/dendrite-monolith
docker build . --target polylith -t matrixdotorg/dendrite-monolith
docker build . --target demo-pinecone -t matrixdotorg/dendrite-demo-pinecone
docker build . --target demo-yggdrasil -t matrixdotorg/dendrite-demo-yggdrasil
```
