  [CSSPGO][Preinliner] Set default value of sample-profile-inline-limit-max to 3000

The default value of sample-profile-inline-limit-max is defined as 10000 in sampleprofile.cpp. This is too big for cspreinliner which works with assembly size instead of IR size. The value 3000 turns out to be a good tradeoff. Compared to the value 10000, 3000 gives as good performance and code size, but lower build time.
