2696: clear warnings better and separate warning count from actual warnings

This PR cleans up the logic surrounding warnings and clearing them.

The important part was separating the number of "new" warnings from the list of warnings themselves.

Every query should clear out the warnings from the previous query. The exception is show warnings, which only clears the "count" of warnings.

When a server runs a query that produces a warning, it immediately calls show warnings. Since the show warnings query itself should NOT clear the warnings, the warning count would always be > 0, and incorrectly indicate that show warnings produced a warning. This causes an infinite loop in .NET. Now, we always clear the warning count, and only clear the warnings themselves when the query is not show warnings.

We've also had this weird problem of having to double clear warnings, which this should address.

fixes:

Connector/NET: A warning causes stack overflow dolthub/dolt#8440
warnings are not clearing from running the same queries multiple times dolthub/dolt#6921


2695: add view column information to information_schema.columns

This PR has information_schema reparse create view statements to fill in missing information for the information_schema.columns table. There maybe small differences in column type for more complex views, but should be fine.

Implementing using view.TextDefinition would be slightly easier/cleaner, but for some reason its sometimes empty? Seems like something to do with fragments on dolt side.

fixes: information_schema.columns does not contain all associated view information dolthub/dolt#3168
2692: alter underlying enum values to preserve enum strings

fixes: Dolt doesn't update enum/set values when the type is changed dolthub/dolt#7472
2691: Bug fix for DESCRIBE with a schema name
2690: only check references for updated columns

fixes: When updating rows, Dolt requires all values in the row to satisfy constraints, not just the values changed dolthub/dolt#2690
2689: Support for schema name in SHOW TABLE statements

This provides support for show tables from public and show table from mydb.public in postgres dialects.
