[TextField] Semantics label + InputDecoration.prefixText + InputDecoration.labelText + InputDecoration.hintText Automatically Added to Voice Access Input

[harperl-lgtm]

b/227994145

Steps to Reproduce

1. Execute flutter run to run the Gallery app (https://github.com/flutter/gallery) on an Android phone
2. Navigate to 'MATERIAL'
3. Navigate to 'Text Field'
4. Turn on Voice Access and use Voice Access to input to one of the Text Fields

Expected results:
Input text matches what the user said.

Actual results:
Semantics label + InputDecoration.prefixText + InputDecoration.labelText + InputDecoration.hintText gets added to user input.

Code sample

https://github.com/flutter/gallery/blob/main/lib/demos/material/text_field_demo.dart

Logs

Issue can be temporarily fixed by setting the onSetText property to an empty function in the Semantics widget here: https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/material/text_field.dart#L1453

Suspected root cause (@chunhtai): https://github.com/flutter/engine/blob/453a60f06a594834f15281cb4f29632075bb59cc/shell/platform/android/io/flutter/view/AccessibilityBridge.java#L888

Note:
'ABC' is the actual voice input, 'Name*' is InputDecoration.labelText, 'What do people call you?' is InputDecoration.hintText;
If we set InputDecoration.prefixText / add label to the Semantics widget mentioned above in TextField.dart, they will also be added to the input.

Which Flutter version did this issue happen on? I tested with the latest Flutter stable and master channels but it didn't reproduce.
I haven't been able to record a demo video yet because the phone recording app will conflict with the Voice Input feature on the keyboard. If you confirm that this issue is still reproducible on the latest Flutter channels, I'll try to record a demo.

@harperl-lgtm I can reproduce this issue on the latest stable and master channels (I was mistaken Voice Access for Voice Input, sorry about this). Labeling this issue for further investigation.
