[perf] vscodeIgnore some unused files to optimize extension size (#1278)

#139

- Ignore some different purpose builds for typescript. We didn't use them.
- Ignore typescript localization. We didn't enable localized diagnostic.
- Ignore large ESM files, We're currently using common js

Brings the size down from 105MB to 42MB.
About typescript localization, it's possible to enable this. So if we want to enable it in the future, we can unignore these files.
