In release mode, switch from page_allocator to c_allocator

[karlseguin]

I'm not sure if the page_allocator was chosen for a specific reason, but I've always heard that the GPA should be used in debug/test, and the c_allocator in release.

I suppose we used the page allocator b/c Zig's doc recommends it with arena.

But indeed using c_allocator is a better option since we link with libc.

before I merge it, @karlseguin can you rebase the branch to run the end-to-end regression tests please?
