Allow filtering Unreal events by their crash_type

[bitsandfoxes]

Resolves #38550
Frontend: #44095

Unreal events have crash_type as part of their Unreal context that originates from ECrashTypeContext.

enum ECrashContextType
{
    Crash,
    Assert,
    Ensure,
    Stall,
    GPUCrash,
    Hang,
    OutOfMemory,
    AbnormalShutdown,
    Max,
}

I'd like to make it possible to filter by this context.

It's discouraged to make changes to Sentry's Frontend and Backend in a single pull request. The Frontend and Backend are not atomically deployed. If the changes are interdependent of each other, they must be separated into two pull requests and be made forward or backwards compatible, such that the Backend or Frontend can be safely deployed independently.
