SDK Crash Detection: Capture SDK-related crashes with specific signatures

[kahest]

Sometimes we want to get insights into crashes that are not caused by the SDK directly and where sentry doesn't show up in any stack frame. It'd be useful for these cases to also capture/forward crashes based on specific signatures, even if they don’t include sentry in the stack trace.

At the moment, I suggest capturing the following signatures (all related to Android Runtime tracer crashes):

• /apex/com.android.art/lib64/bionic/libc.so with stack.function pthread_getcpuclockid (for 2604)
• /apex/com.android.art/lib64/libart.so with stack.function art::Trace::StopTracing (for 3561)
• /apex/com.android.art/lib64/libart.so with stack.function art::Thread::DumpState (for 3653)
