+[FIRApp registerInternalLibrary:withName:] take too much time

[shanksGuo]

Feature proposal

• FIRApp: remove +load or reduce the time cost of [FIRApp registerInternalLibrary:withName:]

As image shown below, [FIRApp registerInternalLibrary:withName:] in App launch Initializing phase take 78ms, it is too much for our App launch! So, could you optimize this.

Wish you accept this suggestion!

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Sadlly, according to my multi tests, the block time can be up to 100ms -_-

The time cost is very important to our App, hope you can handle this ASAP. Thanks in advance!

@shanksGuo Thank you for the detailed report pointing out to the exact place that causes issue for your application! We implemented some optimizations to avoid the slow part running from +load and running it on a background queue.

Unfortunately it's a bit too late to include the change to the next release, so it'll be include to the release after. In the meanwhile we will appreciate your feedback if you could test the #6919 changes from the branch.

@maksymmalyhin Thank you. By the way, I have a question, I'm on release-7.0 now, if I want to fetch the code optimized, which branch can I use?
