2155: Allow BLOB/JSON/TEXT columns to have literal default values (MariaDB compatibility)
Technically, MySQL does NOT allow BLOB/JSON/TEXT columns to have a literal default value, and requires them to be specified as an expression (i.e. wrapped in parens). We diverge from this behavior and allow it, for compatibility with MariaDB.
While testing with a binary literal, I noticed that SQLVal was converting that value to "BLOB" instead of the actual binary content, so I fixed that one, too.

2152: Update RangeTree MaxUpperBound when removing nodes
Verification code from in the last RangeTree related PR caught some bad ranges in the sqllogictests.
The cause was not properly updating the MaxUpperBound in nodes for the rangetree when performing a remove operation, which led to missing connections when pruning ranges.
This also prints MaxUpperBound in the String/DebugString methods for easier debugging.

289: add partial support for ':=' assignment operator
This PR adds support for set expressions and assignment expressions.
Does not include support for select expressions, as it's deprecated on MySQL
