Additional speech needed when navigating percussion notation

Issue type

Accessibility issue (e.g. for keyboard-only or screen reader users)

Description with steps to reproduce

Currently a blind user has no easy way to know what their percussion music looks like in print on the score. For other instruments this added info is not required as as long as you know the clef you know the space/line position. However, as percussion scoring can vary this info is required.

This could be done in one of two ways (or both):

1. Add the additional info of line/space, stem direction and note head shape at the end of the string of info spoken as you arrow along the score notes. So for example "Bass Drum 1, crotchet, voice 2, bar 1 beat 1, space 1, filled note head, stem down". As voices are announced maybe the stem down isn't necessary, but the line/space is the crucial missing bit and the X or circled heads.
2. These could be discovered by going to the Percussion panel and changing to Notation Preview instead of pad name. See #32788.

Start by reproducing the issue in MuseScore Studio 4.7 beta with NVDA, checking the speech produced while arrowing through percussion notes. Compare that with the Percussion panel's Notation Preview option described in #32788; the work is done when blind users can discover the relevant percussion notation details, including line or space and notehead shape.
