Fix GetGlobalVariableOffset with tagged pointer in aarch64
Tagged pointer for aarch64 since Android R would lead top byte to have
random values. For example of a symbol from libart.so in a hwasan
enabled device in Android R:
1490: 8800000000b094a0 144 OBJECT GLOBAL 24 __dex_debug_descriptor
We need to mask off the top byte so that the address range comparison
would work as intended.
Test: Ran new unit test
