[Build] Migrate the build environment and Code Signing (AppVeyor CI and SignPath)

[gnh1201]

Summary

We are currently pursuing code signing for the binaries (DLL and EXE files) included in WelsonJS. To achieve this, it is necessary to migrate the build environment to a CI (e.g., AppVeyor, GitHub Actions, etc.). This issue has been created to address the required tasks.

Here are the tasks that need to be completed for this:

• [x] Remove the checked-in binaries
• [x] Migrate the build environment to CI (e.g., AppVeyor, GitHub Actions, etc.)
• [x] Code Signing test with SignPath
• [x] Code Signing to release the binaries

I bulit with AppVeyor. I have confirmed that the artifacts were generated correctly.

I am currently in discussions with the "SignPath Foundation" for code signing. SignPath is one of the certification authorities that can issue code signing certificates for open source projects.

I received notification from SignPath that an OSS Organization account has been created. I am currently proceeding with the subsequent tasks.

I confirmed today that the certificate was successfully received. The code signing process has been completed through SignPath. I am grateful for their sponsorship.
