Initial version of a devcontainer for Verible

[kbrunham-intel]

Initial version of the .devcontainer/ directory and configuration.

This devcontainer uses a Dockerfile based on the Microsoft CPP container, augmented to install Bazel, clang-format, and clang-tidy.

With the devcontainer, developers can clone the repo, and open it within a standard container definition.

Hi @corco : I don't have write access to the repo, so I can't merge this PR. Can you please merge it or grant me write access?

Thanks.

[kbrunham-intel]

@corco / @hzeller : Please merge as I don't have write access.

[hzeller]

Can you add a README to the directory that explains what this is for possibly with links pointing to documentation ?
It looks like a editor configuration for a specific (vscode ?); so for everyone else they then can see if this is relevant for them.

[corco]

Please add the environment variable USE_BAZEL_VERSION with value "6.5.0" in the devcontainer.json. Right now the devcontainer would use bazel 7.0 which is not able to compile verible. That environment variable should make it use a compatible bazel version

[hzeller]

Recent changes should make it possible to compile with Bazel 7, so maybe the USE_BAZEL_VERSION might not be needed.

Since I can't test the devcontainer stuff I can't test that myself. Passing on to @corco (who can have a look next week when back)

@kbrunham-intel : can you add a README in the directory briefly explaining what it is for ?

Looks good. Even though it is for a specific editor, it does not seem to be to much of an additional burden to maintain(I usually would recommend just using the shell.nix for the relevant dependencies).

Anyway, before merge I'd remove the comments in the json file first, as the json spec does not allow for comments.
Just add the relevant link in the README.md, e.g.
"The Dockerfile defines the environment to use, with json configuration according to https://aka.ms/devcontainer.json for the VSCode editor".

[hzeller]

Thanks, merged.
