perf(mercurial): improve performance of hg_prompt_info (#7929)

Browse source 
Replaced two different calls of hg with one `hg --id --branch` for retrieving
information whether we're in a repo (will be empty if not), whether the repo is
dirty (revision id will contain "+" if there are uncommitted changed), and the
branch name.

Closes #6197
