Grant Shell ability to clear instant app

It already has grant to clear data of application, and instant
application is a subset of that.

This permission is needed for correct performing of the test:
`android.appsecurity.cts.InstantCookieHostTest#
testCookieUpdateAndRetrieval`.

Bug: 77849650
Test: run several times in a row (at least two), note that first time
      on the fresh DUT the result is always successful:
      cts-tradefed run commandAndExit cts-dev \
      -m CtsAppSecurityHostTestCases \
      -t android.appsecurity.cts.InstantCookieHostTest#testCookieUpdateAndRetrieval
