Refactoring related to ReactPy v2.0.0

[shawncrawley]

Description

My attempt at refactoring to align with ReactPy v2.0.0. This depends upon the refactors that were also made to reactpy-router to align with ReactPy v2.0.0 (see PR for that here).

There are a few remaining fixes/updates that I haven't been able to figure out yet. These are the related tests that fail when I run them locally:

• tests\test_app\tests/test_components.py:230 ComponentTests.test_component_use_user_data
• tests\test_app\tests/test_components.py:286 ComponentTests.test_component_use_user_data_with_default
• tests\test_app\tests/test_components.py:685 ComponentTests.test_form_basic
• tests\test_app\tests/test_components.py:779 ComponentTests.test_form_bootstrap
• tests\test_app\tests/test_components.py:817 ComponentTests.test_form_orm_model
• tests\test_app\tests/test_components.py:565 ComponentTests.test_pyscript_0_hello_world
• tests\test_app\tests/test_components.py:575 ComponentTests.test_pyscript_1_multifile

The first two are related to open discussion here. As for the rest, I still have no idea what the problem is after digging for hours.

This is no longer needed. An update to pyscript has deprecated the py-script HTML tag. The correct syntax now uses a normal script tag.

For example: <script type='py'>{EXAMPLE_CONTENTS}</script>.

See pyscript_component_html in reactpy core as an example.
