Reland: Oilpan: Reduce the size of heap_page.h.

heap_page.h is used in 6,000+ compilation units, and this CL reduces its
estimated expanded size from 1.72MB to 1.40MB.

This CL relands https://chromium-review.googlesource.com/1104080 .
With the original code, GetRandomMagic() was folded into GetMagic(), and
GetMagic() was not folded into IsValid().
With https://chromium-review.googlesource.com/1104080,
ComputeRandomMagic() was not folded into GetMagic(), and GeMagic() and
IsValid() were folded into IsValid() callsites.  So the binary size
increased.
With this CL, GetMagic() isn't folded into IsValid() like the original
code. So this CL won't increase the binary size, and should not have
performance regression.
