Remove android stack_size_test (#153695)

This test expects to run on 32-bit hardware, but the devicelab no longer
has 32-bit Android hardware. In particular, the test contains hand-coded
32-bit arm assembly for reading the stack pointer from Dart code via
`dart:ffi`.

This test was added in response to a framework change that caused stack
frames to be larger than expected while building widgets, leading apps
to crash with StackOverflow exceptions unexpectedly. Since then (>3
years ago) this test has not prevented any similar issue, so I believe
deleting it rather than fixing it is a better use of resources.
