Port git extension to use esbuild

[mjbvz]

Fixes #296355

Required more changes as esbuild won't inline const enums from d.ts files

[Copilot]

Pull request overview

This PR migrates the git extension from webpack to esbuild. The main challenge was handling const enums defined in the git.d.ts API file, which esbuild cannot inline from declaration files. The solution creates a runtime constants file that provides Object.freeze equivalents of the const enums while maintaining type safety through TypeScript's satisfies operator.

Changes:

• Created git.constants.ts to provide runtime equivalents of const enums (RefType, Status, ForcePushMode, GitErrorCodes) from git.d.ts
• Updated all imports throughout the extension to use import type for types and import runtime values from git.constants
• Replaced webpack configuration with esbuild configuration
• Added ESLint rule to enforce the import pattern and prevent future violations
