Add `read-configuration` subcommand to output a merged devcontainer configuration

Note: If we implement option 1 from https://github.com/coder/envbuilder/issues/211, we could punt this feature for the time being.

This feature is a pre-requisite for generating a computed devcontainer.json for use by e.g. coder modules. This can help resolve issues like https://github.com/coder/envbuilder/issues/68 where a list of extensions needs to be available during installation of vscode, code-server, etc.

This commands main purpose is to output a merged configuration based on the projects devcontainer.json as well as configuration introduced by features.

A logical approach would be to mimic @devcontainer/cli output. Doing so would make envbuilder a versatile tool for interpreting devcontainer features, and potentially a drop-in single binary alternative.

Here's an example output from @devcontainer/cli when run against the microsoft/vscode repo.

devcontainer read-configuration --include-merged-configuration --log-format json --workspace-folder /tmp/envbuilder/vscode

Under .configuration the only new field is .configuration.configFilePath. Otherwise this is the project devcontainer.json as-is. The rest: .workspace, .featuresConfiguration and .mergedConfiguration are all added by read-configuration (and the merged config flag).

For this issue, we're mainly interested in implementing .mergedConfiguration.
