[WIP] CNDB-15608 port CASSANDRA-18673 to reduce disk usage of row-aware indexes

[k-rus]

The PR is still in initial state. It compiles and majority of tests are expected to succeed.
It removes usage of Trie for primary key component, which requires additional adjustments. Also it might not be really acceptable.
There are many more small issue to fix:

• Investigate and fix where Trie based API of sorted terms were used (as mentioned above)
• Noticed memory leaks
• Reported disk size is 0 in some cases in SAI disk size test
• Double check commented or remove code
• Investigate removed benchmarks
• May be move IndexFileUtils as in C*
• Introduce TokenOnlyPrimaryKey class as in C* (improves isTokenOnly implementation)
• May be move out inner impl classes from IndexDescriptor as in C*
• Port bug fixes from C*
