feat: devcontainer (#2156)

# Description

This PR presents a complete devcontainer environment for building with
the CoW Protocol services repository.

# Changes

- [x] Build using the latest standard `rust` devcontainer
- [x] Enhance the `rust` devcontainer with `gdb`, `valgrind`, and
`heaptrack`
- [x] Installs both `stable` and `nightly` toolchains, automatically
configuring rust-analyzer to use `nightly` for `rustfmt`
- [x] Includes `docker`, `postgresql-client` and `node` for development
- [x] Configures the `zsh` shell
- [x] Adjusts docker settings to enable trace capabilities for profiling
development

## How to test

1. Open in VS Code and take it for a spin

**Caution**: This can take a while to build the container environment on
first start.
