perf(blame): run blame for entire file instead of per line
Previously current_line_blame would run a git-blame process per line (via the `-L` flag) in an attempt to be more efficient. However after some investigation it seems that running git-blame for the entire file rarely exceeds 2x the time it takes to run for a single line, even for large files. This change alters current_line_blame to run git-blame for the entire file after each buffer edit and caches that in memory. This makes the first git-blame after an edit ~2x slower, but makes any cursor movements after that instant. A follow-up to this would be for current_line_blame to track buffer updates to avoid the cache needing to be invalidated on every edit.
