Summary Improve performance of increasing HTMLSelectElement::length

Consider merging https://chromium.googlesource.com/chromium/blink/+/c0f9edf107acd697011236dfe9855141b59e18a2 It was possible that a CSS ruleset made update of HTMLSelectElement::length O(N^2). This CL improve it to O(N) by AttachLazily. Before Blink r153385, fast/forms/select-max-length.html took 3.8s on my machine. After Blink r153385, it took 20s. After this CL, it will take 1.8s.

rnwia@webkit.org - I don't think we have "AttachLazily" and we removed it?

AttachLazily isn't a thing anymore.
