Add support of sql dialect while sql generation

[snuyanzin]

The PR adds supports of several SQL dialects
e.g. for postgres there is " as a sql quote identifier , for MSSQL it's [], for some other dbs it's `
e.g. for postgresql

INSERT INTO "MyTable" ("key") VALUES ('value');
INSERT INTO "MyTable" ("number") VALUES (123);
INSERT INTO "MyTable" ("number") VALUES (123.0);

for MSSQL

INSERT INTO [MyTable] ([number]) VALUES (123.123);
INSERT INTO [MyTable] ([boolean]) VALUES (true);

to generate the following code could be used

SqlTransformer<?> transformer = new SqlTransformer.SqlTransformerBuilder().dialect(SqlDialect.MSSQL).build();
transformer.generate(Schema.of(field("number", () -> 123.123)), 1);

possible output

INSERT INTO [MyTable] ([number]) VALUES (123.123);

same for postgres

SqlTransformer<?> transformer = new SqlTransformer.SqlTransformerBuilder().dialect(SqlDialect.POSTGRES).build();
transformer.generate(Schema.of(field("number", () -> 123.123)), 1);

output

INSERT INTO "MyTable" ("number") VALUES (123.123);
