Add Bazel build support for WasmEdge-go (Fixes WasmEdge/WasmEdge#2162)

[kalamkaar9404]

This PR implements Bazel build support for WasmEdge-go using rules_go and Gazelle.

Key Changes:

Added root WORKSPACE and BUILD.bazel files.

Generated package-level BUILD.bazel files using Gazelle.

Updated README.md with instructions for Windows users to link the WasmEdge C library via Bazel.

Updated CI workflow to include the new feature branch.

Verification: Build success verified via GitHub Actions on my fork for both Ubuntu 24.04 and MacOS 14 across Go versions 1.22 and 1.23.

Fixes #2162

Hi @hydai , I’ve completed the Bazel support for WasmEdge-go as discussed in #2162.

I have verified the build structure on Windows and confirmed that the CI passes on my fork. This PR includes:

WORKSPACE and root BUILD.bazel configuration.

Updated README.md with Windows CGO linking steps.

CI workflow updates to support this branch.

Could you please approve the workflows to run and take a look at the changes? Thank you!

It's so strange that you're adding so many files under this folder:

I don't think this should be committed to the repository.

[kalamkaar9404]

Hi @hydai, thank you for your feedback! I have updated the PR to:

Remove the bazel-* output directories that were accidentally committed.

Update the .gitignore to prevent them from being tracked.

I have verified on my fork that the CI build still passes successfully for all platforms with these changes. Please let me know if there are any other adjustments you'd like me to make!

[hydai]

I think you should check the document about Bazel. Trying to add bazel-out to a git source tree is quite unusual.

Hello @hydai
I have made the requested changes can you please look once now?

[kalamkaar9404]

Hi @hydai, I have addressed the mentioned issues:

I have aligned the version to 0.14.0 across MODULE.bazel, README.md, and the CI workflow to match the current latest release.
I have removed the patch file/folder and moved the cdeps and repository logic directly into the Bazel files.
I have fixed the missing newline in main.go and removed redundant lines/comments in build.yml.

I request you to look into it once.
Thank you

Hi @hydai, I have added multi-platform support by including all the necessary URLs. I previously made changes to build.yml to address build errors, but based on your feedback, I understand that build.yml does not require modification. Therefore, I have reverted it to its original state and have only applied the necessary changes to the MODULE.bazel and README.md files. Does this look fine to you?

Hello @hydai,
Can you please review this once?
Thank you

LGTM.

Please squash your commits into only one.

[kalamkaar9404]

Hi @hydai, I have squashed the commits into a single signed-off commit. The PR is now ready for your final review.
Thank you for your help!

May I ask which workflow the Bazel build falls under?
I didn't find the testing jobs for these new building system.

[kalamkaar9404]

Hi @hydai,
Can you please check once now? I have done the testing locally and added in the workflow fixing the test errors.

[kalamkaar9404]

The tests are passing on my setup

[kalamkaar9404]

Hi @hydai,
The CI failures are due to the missing enum.inc C header during the cgo build step. I have modified the MODULE.bazel file.

[kalamkaar9404]

Hi @hydai,
I found that the macOS runner is arm64, but the previous Bazel config was fetching the x86_64 SDK. I have updated the MODULE.bazel to fetch the aarch64 Darwin release, which resolves the 'symbol not found' linker errors. This should finalize the cross-platform Bazel support.

[kalamkaar9404]

Hi @hydai, I have updated this PR with a fully verified and workable Bazel configuration. I apologize for the previous non-functional pushes; I have now confirmed that these changes pass all 4 matrix jobs (Ubuntu 24.04 and MacOS 14 across Go 1.22.x and 1.23.x) on my fork (I have attached the image for the same). Thank you for your patience.

[kalamkaar9404]

Hello @hydai,
I have kept the original build step as requested.
I have tested the changes on my fork and the build is now passing. I removed the unused import "C" from limit_test.go. Since that file strictly tests Go logic and does not use any C types, the import was unnecessary and was causing the build to fail.
Can you please review?

[kalamkaar9404]

Hello @hydai,
Can you please let me know if the version is correct now? Are there any other changes required?
