* chore: keep session pool ordering when pinging

Pinging sessions would move the sessions that were pinged to either the
front or the back of the pool (dependingin the session pool
configuration), instead of keeping the sessions in the place where they
were when being pinged. Bringing a session that is pinged to the front
of the pool means that we will prefer using a session that has not
really been used for a while, other than for the ping. Keeping the
sessions in place is therefore preferable.

To enable Direct Access, [both `setAttemptDirectPath` and `setAttemptDirectPathXds` should be called](https://togithub.com/googleapis/sdk-platform-java/blob/4b44a7851dc1d4fd2ac21a54df6c24db5625223c/gax-java/gax-grpc/src/main/java/com/google/api/gax/grpc/InstantiatingGrpcChannelProvider.java#L373-L386) for gax to append the correct google-c2p scheme.

This PR adds a env var `GOOGLE_SPANNER_ENABLE_DIRECT_ACCESS` to control the enable/disable of Direct Access. When it is true, it calls `setAttemptDirectPathXds` which effectively turns on Direct Access (as `options.isAttemptDirectPath` is by default true and we don't need to call `setAttemptDirectPath` again).

Move the PostgreSQL skip methods from the PostgreSQL parser to the
abstract parser. This is step 1 in refactoring the GoogleSQL and
PostgreSQL parser so they can share more code. The eventual goal is to
allow the GoogleSQL parser to be able to handle SQL string without
having to remove the comments from the string first.

* Use `TransactionOption` as return type instead of `TransactionOption`

Generalize the various skip methods so these can be used for both dialects. Each dialect implements a number of abstract methods to indicate what type of statements and constructs they support. These methods are used by the generalized skip methods to determine the start and end of literals, identifiers, and comments.

This is step 2 of the refactor that is needed to share more of the code between the SpannerStatementParser and PostgreSQLStatementParser.

Keep all comments in the SQL string in place when converting positional parameters to named parameters. This reduces the amount of string operations that are needed for each query that is executed, and also enables actually sending comments from the client to Spanner when using positional parameters (e.g. in JDBC).

This is step 3 in the refactoring to share more code between the SpannerStatementParser and PostgreSQLStatementParser.

Adds an 'endpoint' connection URL property for the Connection API.
This property can be used instead of adding the endpoint to the host
group part of the Connection URL, which again removes the need to
actually change the connection URL when connecting to for example
the emulator from the JDBC driver. The latter can instead just add
the endpoint to the Properties set that is given to the JDBC driver.

Adds support for max_commit_delay to the Connection API:
