[Java] Normalize exceptions to AdbcException subclasses

### What feature or improvement would you like to see?

Although most Adbc methods throws `AdbcException`, there are several places in ADBC interfaces where methods throws `Exception` (notably for `close()` methods) or `IOException`. Similar to JDBC API, all exceptions should be normalized around `AdbcException` to make API consistent.

It would be an incompatible API change though. When updating methods from `Exception` to `AdbcException`, this would be a source incompatible change but a binary compatible one. However when changing from `IOException` to `AdbcException`, it would be a source and binary incompatible change.
