test(e2e): disable GWP-ASan in AndroidApp to avoid Hermes x86_64 crash

Refs #499

Problem

The Android Expo E2E jobs sometimes crash with a native SIGSEGV. Over the last week this happened in 2 of 36 completed Expo jobs, and the failure shows up as "Detox can't connect to the app". Both crashes have the same stack:

#00 libc.so  android_unsafe_frame_pointer_chase
#01 libc.so  gwp_asan::AllocationMetadata::CallSiteInfo::RecordBacktrace
#02 libc.so  gwp_asan::GuardedPoolAllocator::deallocate
#03..       libhermesvm.so
#12         libhermesvm.so (hoost_make_fcontext)

This is a known Hermes V1 issue on x86_64: facebook/hermes#1873 and facebook/hermes#2225. GWP-ASan samples a free() that runs on a Hermes fiber stack. Its stack walker then follows a bad frame pointer into unmapped memory and crashes. It isn't a memory bug in the app.

The upstream fix (facebook/hermes@73f9af39) is in Hermes 260318099.x. Our Expo 58 build already ships 260318099.0.3 (I matched the Build ID from the crash log) and still crashed, so upgrading Hermes isn't enough.

Change

Set android:gwpAsanMode="never" on the AndroidApp <application>, with a comment linking the Hermes issues. This only turns off GWP-ASan sampling for the example app.

Notes

• This is separate from test(e2e): hide ANR dialogs on the Android E2E emulator #501, which fixes the ANR dialog failures.
• The crash rate is ~6%, so a few green runs won't prove much on their own. This PR rests on the upstream analysis, not on a CI A/B test.
• Revisit once Hermes ships a fix that also covers 260318099.x.
