Bug when transpiling any_value to Spark and Presto.

[edwinlei]

Fully reproducible code snippet
sqlglot.parse_one("select any_value(c1)").sql(dialect="presto") returns

SELECT ANY_VALUE(c1)

instead of

SELECT ARBITRARY(c1)

Similarly sqlglot.parse_one("select any_value(c1)").sql(dialect="spark") returns

SELECT ANY_VALUE(c1)

instead of

SELECT FIRST(c1)
