chore: Android SR - cleanup privacy settings (#341)

## Summary

1. Rename maskSensitive to maskBySemanticsKeywords and set default false
2. Changes default `maskText` to `false`
3. removes `maskAdditionalMatchers` (they might return later under
different name and rework to be more universal)

<!--
Ideally, there is an attached GitHub issue that will describe the "why".

If relevant, use this section to call out any additional information
you'd like to _highlight_ to the reviewer.
-->

## How did you test this change?

<!--
Frontend - Leave a screencast or a screenshot to visually describe the
changes.
-->

## Are there any deployment considerations?

<!--
 Backend - Do we need to consider migrations or backfilling data?
-->

> [!NOTE]
> Streamlines Session Replay masking configuration and docs.
> 
> - Renames `maskSensitive` to `maskBySemanticsKeywords` and wires it
into `asMatchersList()`; default `false`
> - Changes `PrivacyProfile.maskText` default to `false`
> - Removes `maskAdditionalMatchers`; drops corresponding `addAll(...)`
in `asMatchersList()`
> - Restricts matcher properties (`viewsMatcher`, `xmlViewIdsMatcher`,
`textInputMatcher`, `textMatcher`, `sensitiveMatcher`) to `internal`
> - Minor KDoc tweaks and parameter order; `maskImageViews` remains,
moved after lists
> - README updates to show new toggles and example `PrivacyProfile`
usage
>
