Ariel Mashraki b23a0e8554 dialect/sql/sqlgraph: avoid creating tx blocks for single DELETE statements ...

In PostgreSQL, every statement is executed within a transaction. Therefore, we can avoid
creating transaction blocks manually (group of statements surrounded by BEGIN and COMMIT)
for DeleteNodes operation as it's implemented with a single statement.

Benchmark for 4000 operations was improved from:

	14.54s      7270455 ns/op    3702 B/op     81 allocs/op

To:

	5.36s      2679935 ns/op    2864 B/op     59 allocs/op

MySQL and SQLite share the same behavior. Please see https://github.com/ent/ent/pull/1858
