2366: Update README with latest sample code from _example/main.go

The latest release of go-mysql-server requires a different way of instantiating the database server. Notably, a function that provides sessions must now be provided.

This change updates our README with the latest working example code from _example/main.go.

2362: Feature: last_insert_uuid() function

UUIDs are often used in place of auto_increment IDs, but MySQL doesn't provide an easy way to get the last generated UUID that was used in an insert. This change introduces a new function, last_insert_uuid() that operates similarly to last_insert_id(). For a column identified as a UUID column, callers can use last_insert_uuid() to retrieve the last generated UUID value that was inserted into that column. In order to be considered a UUID column, a column must be part of the primary key and it must meet one of the following type signatures:

VARCHAR(36) or CHAR(36) with a default value expression of UUID()
VARBINARY(16) or BINARY(16) with a default value expression of UUID_to_bin(UUID()) (optionally, the swap_flag for UUID_to_bin may also be specified)

Example usage:
create table t (pk binary(16) primary key default (UUID_to_bin(UUID())), c1 varchar(100));
insert into t (c1) values ("one"), ("two");
select last_insert_uuid();
select c1 from t where pk = uuid_to_bin(last_insert_id());

2360: fix special case for now() string

The BATS tests import-mysqldump.bats was failing due to a recent string replace case added by fix ON UPDATE CURRENT_TIMESTAMP precision dolthub/go-mysql-server#2357.

I didn't account for when NOW() would be used with other functions inside a DEFAULT column expression, and was replacing the "NOW(" with "CURRENT_TIMESTAMP(". This was causing problems as we reparse ColumnDefaultExprs, resulting in unparenthesized default expressions, which threw an error.
2359: unskip fixed tests

There are some tests that are fixed, but we haven't unskipped them.

Additionally, this cleans up the way we skip certain tests so that it is more consistent.
2357: fix ON UPDATE CURRENT_TIMESTAMP precision

I had mistaken assumed that MySQL did not allow any precision arguments for NOW() (and synonyms) for column DEFAULT and ON UPDATE expressions. It turns out MySQL only requires that the column type precision match the expression.

Additionally, we did not perform these error checks for DEFAULT expression, so now we do.
