0768f424 - Reduce allocation size in test Gather_oveflow_check from 4GiB to >2GiB (#27483)

Reduce allocation size in test Gather_oveflow_check from 4GiB to >2GiB (#27483) ### Description This PR reduces the size of the memory allocation for expected outputs from ~4GiB to ~2GiB in the Gather_overflow_check test. The updated test still verifies that the integer overflow fix from PR https://github.com/microsoft/onnxruntime/pull/27444 is valid. That is, that the CPU Gather operator correctly handles output tensors with element counts that exceed INT32_MAX. Changes: - Reduced test dimension from 65537 to 46341 (output shape from 65537×65537 to 46341×46341), which results in a total number of elements that is just over INT32_MAX, which is required to test the bug fix. - The peak memory usage is reduced to ~4GiB + overhead. - Increase Android emulator memory to 5GiB (from 4GiB) to be able to run the test. ### Motivation Android CI fails to run the unit test introduced in https://github.com/microsoft/onnxruntime/pull/27444 due to memory usage that exceeds the Android emulator's default memory of 4GiB. This PR lowers the peak memory usage of the unit test and increases the Android emulator's memory by 1GiB.
