Chain StringBuilder.append() calls

org.openrewrite.java.cleanup.ChainStringBuilderAppendCalls String concatenation within calls to StringBuilder.append() causes unnecessary memory allocation. Except for concatenations of String literals, which are joined together at compile time. Replaces inefficient concatenations with chained calls to StringBuilder.append().
