Panic UnsafeAppendBoolToBitmap for dictionary and REE builders

For more context: https://github.com/apache/arrow-go/pull/558/changes#r2758798540

This commit makes `UnsafeAppendBoolToBitmap()` for `dictionaryBuilder`
and `RunEndEncodedBuilder` panic. The current implementation pulled
from `arrow/array/builder.go` would leave the builders in invalid states
that would panic when trying to finish a record batch.
