Add support for immutable fields in core records
* module/ice-9/boot-9.scm (make-record-type): Allow (mutable NAME)
or (immutable NAME) as a field name, and record field mutability in a
bitfield.
(record-modifier): Throw an error if the field isn't mutable.
* test-suite/tests/records.test ("records"): Add tests.
* doc/ref/api-data.texi (Records): Update.
