Enable/disable the 'Report normalized' checkbox when opening the speech panel (#16810)
Fix-up of #16521.
Summary of the issue:
When opening the speech settings panel, the checkbox "Report 'Normalized' when navigating by character" is enabled, no matter the value of the "Unicode normalization" combo-box.
Description of user facing changes
When opening the speech settings panel, the checkbox "Report 'Normalized' when navigating by character" will be enabled or disabled (greyed out), depending on the value of the "Unicode normalization" combo-box, as it is already the case when the selection of this combo-box is modified.
Description of development approach
As done for "Ignore blank lines for line indentation reporting" checkbox in Document formatting settings, explicitly call the .Enable method when the panel is initialized.
