zeroing BitMemoryRegion buffer.
WriteMethods use ForMethodBitmapHotnessFlags to store bit, But it may
not store bit on some conditions.
For scudo in Android S zeroing heap is by default. so it works normally.
But if MALLOC_ZERO_CONTENTS is false or using jemalloc allocator,
the heap may filled with dirty data. so we should zero BitmayRegion
buffer.
Test: malloc_svelte target
run cts -m CtsDexMetadataHostTestCases -t
