feat(profiling): new launch profiling option

[armcknight]

Introduce the new SentryProfileOptions.profileAppStarts option.

I realized I would need to be able to distinguish between continuous profiling V1 with launch profiling enabled and this V2 launch profiling, so I had to rework the way SentryProfileOptions are configured in SentryOptions, so I used a configuration block pattern similar to user feedback and replay, so that I could look for the presence of the configuration by nilchecking it.

Note that while the diff size on this is large, almost all of it is test code.

#skip-changelog; for #4853

Left some comments, and also it seems like compilation fails for some platform, but I couldn't directly comment it. Please see the test annotations
