Subject: pgsql: postgres_fdw, dblink: Validate use_scram_passthrough values

postgres_fdw, dblink: Validate use_scram_passthrough values
The use_scram_passthrough option in postgres_fdw and dblink accepts
only boolean values. However, unlike other boolean options such as
keep_connections, its value was not previously validated.
As a result, commands such as
"CREATE SERVER ... OPTIONS (use_scram_passthrough 'invalid')"
could succeed unexpectedly.
This commit updates postgres_fdw and dblink to validate that
use_scram_passthrough is assigned a valid boolean value, and throw an
error for invalid input.
Backpatch to v18, where use_scram_passthrough was introduced.
