Make summary buffer available at fugitive:// URL

Browse Source 
Using $GIT_DIR/index for the summary buffer has 2 problems:

* It requires a BufReadCmd for all files named "index", necessitating
  special handling for false positives.
* It forces us to resolve ".git" files and symlinks, decoupling us from
  the worktree and thus forcing us to depend on `core.worktree`.  Git
  always sets this when necessary, but users and third-party tooling
  sometimes do not.

Using a fugitive:// URL for the buffer solves both.

This is a large, breaking change, so let's leave $GIT_DIR/index as the
default for now.
