[SyntaxTree] Specialize `TreeTestBase` for `BuildTreeTest` and `MutationsTest`

I think it makes sense to split this into a separate file as well.

If agreed this will be done in a separate patch, because it will also incur the creation of a Synthesis.h.

Currently BuildTree.h is backed by Synthesis.cpp and BuildTree.cpp which I don't think makes a lot of sense

Could we split it into multiple test cases?

TEST_P(MutationTest, RemoveStatement_BinaryExpression) {
  CheckTransformation(
    RemoveStatement,
    "void test() { [[100+100;]] test(); }",
    "void test() {  test(); }");
}

Also consider moving the std::function argument in CheckTransformation to the first position for readability of the call.
