bpo-30993: IDLE - Improve configdialog font page and tests. (#2818) 

* Document causal event pathways in docstring.
* Simplify some attribute names.
* Rename test_bold_toggle_set_samples to make test_font_set fail.
* Fix test_font_set so not order dependent.
* Fix renamed test_indent_scale so it tests the widget.

Fonts: Enable users to provisionally change font face, size, or
boldness and to see the consequence of proposed choices. Each
action set 3 options in changes structuree and changes the
corresponding aspect of the font sample on this page and
highlight sample on highlight page.
Enable users to change spaces entered for indent tabs.
Fontlist: mouse button 1 click or up or down key invoke
on_fontlist_select(), which sets Var font_name and calls
set_samples.
Tk Variables:
font_name: Font face.
font_size: Font size.
font_bold: Select font bold or not.
Note: these 3 share var_changed_font callback.
space_num: Indentation width.
Sizelist: clicking the menubutton opens the dropdown menu. A
mouse button 1 click or return key invokes an internal command
which sets Var font_size and calls set_samples.
Data Attribute:
edit_font: Font with default font name, size, and weight.
Bold_toggle, clicking the box toggles font_bold and calls
set_samples.
Methods:
load_font_cfg: Set vars and fontlist.
on_fontlist_select: Bound to fontlist button release
or key release.
set_samples: Notify both samples of any font change.
load_tab_cfg: Get current.
Setting any of the font vars invokes var_changed_font, which
adds all 3 font options to changes. Set_samples applies a new
font constructed from the font vars to font_sample and
highlight_sample on the hightlight page.
Tabs: Enable users to change spaces entered for indent tabs.
Changing indent_scale value with the mouse sets Var space_num,
which invokes var_changed_space_num, which adds an entry to
changes.
Load_font_cfg and load_tab_cfg initialize vars and widgets from
idleConf entries.
