Implement bit slice iterator for big endian platforms

*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-10535

Implement big-endian support for bit slice iterators in the arrow arrays, also allow storing and interpreting data as big-endian.

Start by locating the bit slice iterators in the arrow arrays and inspect how their current byte ordering is handled. Done means bit slice iteration works on big-endian platforms and array data can be stored and interpreted as big-endian.
