Drop vergen_git2 dependency (#36439)

Manually call `git rev-parse --short HEAD` to retrieve the commit hash,
instead of using Emitter from vergen_git2. This helps remove
dependencies and shorten compile time.

Testing: It doesn't require tests because it is a refactoring for
removing dependencies
Fixes: #36435
