Remove need for QUERY_ALL_PACKAGES

[Kaljurand]

The Google Play Support does not like the QUERY_ALL_PACKAGES permission and has blocked updates to the app in the Store. The need for this permission is described in:

K6nele/app/src/main/AndroidManifest.xml

Lines 43 to 51 in c325c6a

	<!-- TODO: try to avoid having to request this permission (and then enable QueryAllPackagesPermission)
	Android v11. We query packages for several reasons:
	1) finding speech recognizer providers (this query is declared below in the queries-section)
	2) finding TTS service providers (this query is declared below in the queries-section)
	3) listing apps (with icon and launch intent) that have previously launched Kõnele
	4) launching intents (e.g. setting the alarm or opening maps) via rewrites
	It is unclear if use-cases 3 and 4 could be instead declared via the queries-section.
	-->
	<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" />

Possible solutions:

• ask Google Play Support (again) to reconsider
• build a reduced APK for Google Play without this permission, and recommend users to download from other app stores
• review the reasons why this permission is needed, and maybe drop some features if they are not essential (e.g. showing an icon next to a package name)
