**Notes**
Updates the installer (install.py).
* patched distlib (in build_utils) has been removed. The patch we were relying on
has since been made part of the main distlib release, which we already have vendored;
* virtualenv has been updated to latest;
* scripts have been removed, and entry points are used instead;
* install.py code has been cleaned up and simplified. Specifically, standard use of
distlib.ScriptMaker has been put in place;
* INSTALL.md has been updated with a full explanation of the installer, and why a
pip-based installation is not the same as using install.py.

**Notes**
This fixes a regression introduced in `2.34.0`, which causes `rez-context -g` to
fail. The pydot vendor package was updated, and the newer version includes a
breaking change. Where `pydot.graph_from_dot_data` used to return a single graph
object, it now returns a list of graph objects.
