Simple Installer for Unified Directory Structure, Initial Implementation (#1819)

* partially working simple installer

* works on linux

* fix linux requirements files

* read root environment variable in right place

* fix cat invokeai.init in test workflows

* fix classical cp error in test-invoke-pip.yml

* respect --root argument now

* untested bat installers added

* windows install.bat now working

fix logic to find frontend files

* rename simple_install to "installer"

1. simple_install => 'installer'
2. source and binary install directories are removed

* enable update scripts to update requirements

- Also pin requirements to known working commits.
- This may be a breaking change; exercise with caution
- No functional testing performed yet!

* update docs and installation requirements

NOTE: This may be a breaking commit! Due to the way the installer
works, I have to push to a public branch in order to do full end-to-end
testing.

- Updated installation docs, removing binary and source installers and
  substituting the "simple" unified installer.
- Pin requirements for the "http:" downloads to known working commits.
- Removed as much as possible the invoke-ai forks of others' repos.

* fix directory path for installer

* correct requirement/environment errors

* exclude zip files in .gitignore

* possible fix for dockerbuild

* ready for torture testing

- final Windows bat file tweaks
- copy environments-and-requirements to the runtime directory so that
  the `update.sh` script can run.

  This is not ideal, since we lose control over the
  requirements. Better for the update script to pull the proper
  updated requirements script from the repository.

* allow update.sh/update.bat to install arbitrary InvokeAI versions

- Can pass the zip file path to any InvokeAI release, branch, commit or tag,
  and the installer will try to install it.
- Updated documentation
- Added Linux Python install hints.

* use binary installer's :err_exit function

* user diffusers 0.10.0

* added logic for CPPFLAGS on mac

* improve windows install documentation

- added information on a couple of gotchas I experienced during
  windows installation, including DLL loading errors experienced
  when Visual Studio C++ Redistributable was not present.

* tagged to pull from 2.2.4-rc1

- also fix error of shell window closing immediately if suitable
  python not found
