db.mysql function real_query returns proper MySQL error codes, while any stmt method doesn't

[einar-hjortdal]

Describe the bug

When using real_query:

V panic: Table 'peonyDb.country' doesn't exist; code: 1146

When using stmt.prepare:

V panic: db.mysql.SQLError: Table 'peonyDb.country' doesn't exist (1) (INSERT INTO "country" ("code") VALUES (?)); code: 1

Expected Behavior

stmt methods should return proper MySQL error codes to allow for error handling.

Current Behavior

No error code is returned.

Reproduction Steps

Prepare a statement on a non-existing table.

Possible Solution

No response

Additional Information/Context

Can only test on stmt.prepare and stmt.execute because stmt.bind_result_buffer stll does not work and results cannot be fetched. Please check #17957
