add BoringSSL support

[LukasKastern]

This PR integrates boringssl.
I've been using a variation of these changes for a while now.
I would like to upstream these changes to avoid relying on my fork in other projects.

Compile as

zig build -Dtarget=x86_64-windows -Doptimize=ReleaseFast -Dlibpsl=false -Dlibssh2=false -Dlibidn2=false -Dnghttp2=false -Ddisable-ldap -Duse-boringssl=true

And run

./zig-out/bin/curl https://httpbin.org/uuid

Output

{
  "uuid": "1e7c8860-cdab-4e05-881a-763665242b79"
}

Ideally we wait until the following PRs are merged to avoid relying on my forks in the boringssl repository.

• Upgrade to 0.16.0 googletest#6
• Fix package failure occuring when patch step resides in sub-package akunaakwei/zig-patch#1

I just merged a PR that updated googletest to Zig 0.16.0 so this should be unblocked.

I'd prefer to keep the dependencies within the allyourcodebase organization if possible. Which would allow me and other members to more easily contribute if needed. Would you be open to join allyourcodebase and then contribute your boringssl port to it? More information on how to join can be found here:

That makes sense! I'll update boringssl to use the merged googletest and ping kristoff about joining the org and moving the project over.

[LukasKastern]

I moved boringssl to the allyourcodebase org.
Let me know if you'd like me to revert the ca_bundle change or do any other changes!
