Fixes #8406

Summary of the issue:

Multiline text fields in braille should appear hard left on the braille display to allow as much room as possible for the content of the first line.
NVDA already does this for terminals, and anything with the multiline state. However, it does not do it for documents.
This is now a noticeable problem when using UI automation in MS Word, where the controlType for the UIA element for the document is in deed document. When previously using the object model, it was edit, but did have the multiline state.

Description of how this pull request fixes the issue:

Braille now treats documents as being multiline.

Testing performed:

Using NVDA with braille:

• Opened MS Word with UIA enabled.
• Confirmed that the braille display was showing the document's textInfo region hard left. I.e. for a new document there was just a flashing cursor at the start of the display and nothing else.

Known issues with pull request:

None.

Change log entry:

Bug fixes:

• Similar to other multiline text fields, When positioned at the start of a document in Braille, the display is now panned such that the first character of the document is at the start of the display. (UIA in Word: the document should focus hard left in braille #8406)
