* fix: match system schema names case-insensitively

Database names that arrive over a protocol (the MySQL handshake and
COM_INIT_DB, the Postgres startup parameter, the HTTP `db` parameter, the
gRPC dbname header) never reach the SQL parser, which is what lowercases
unquoted identifiers. Since #8062 stopped lowercasing them wholesale,
connecting to `INFORMATION_SCHEMA` in any spelling but the canonical one
fails with "Unknown database" -- including the `USE <db>` that a MySQL
client turns into COM_INIT_DB.

Fold only system schema names to their canonical spelling, so user schema
names keep the case they were created with. `is_reserved_schema_name` uses
the same match, otherwise a quoted `CREATE DATABASE "INFORMATION_SCHEMA"`
creates a schema shadowed by the system one.
