📄 Description

Summary of the Pull Request

Updates our UiaTextRange to treat the last legible character as the end of the buffer. Doing so significantly improves performance of word navigation because screen readers no longer have to take into account the whitespace following the end of the prompt.

This also fixes #7960. This bug was caused by the UiaTextRange occasionally having its _blockRange member set to true. As a result, the screen reader would read the block range of text from "start" to "end" as if it was a block selection created by Alt+Mouse.
