Subject: [PATCH] [cros search service]: Include <cmath> for std::pow()

IWYU. Follow up to commit 2b2ea3c09b ("[cros search service] Move shared
string matching functions to //chrome"), which broke the libstdc++ build:

    ../../chrome/common/string_matching/fuzzy_tokenized_string_match.cc:199:14: error: no member named 'pow' in namespace 'std'
            std::pow(partial_match_penalty_rate, long_start - current - 1);
            ~~~~~^
