HBASE-23705 Add CellComparator to HFileContext (#1062)

Codecs don't have access to what CellComparator to use.  Backfill.

M hbase-common/src/main/java/org/apache/hadoop/hbase/CellComparator.java
 Adds a new compareRows with default implementation that takes a ByteBuffer.
 Needed by the index in a block encoder implementation.

M hbase-common/src/main/java/org/apache/hadoop/hbase/CellComparatorImpl.java
 Adds implementation for meta of new compareRows method. Adds utility
 method for figuring comparator based off tablename.

M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/AbstractDataBlockEncoder.java
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/BufferedDataBlockEncoder.java
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/RowIndexCodecV1.java
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/RowIndexSeekerV1.java
 Comparator is in context. Remove redundant handling.

M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/DataBlockEncoder.java
 Comparator is in context. Remove redundant handling. Clean javadoc.

M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/HFileBlockDecodingContext.java
 Clean javadoc.

M hbase-common/src/main/java/org/apache/hadoop/hbase/io/encoding/RowIndexEncoderV1.java
 Cache context so can use it to get comparator to use later.

M hbase-common/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileContext.java
 Cache cellcomparator to use. Javdoc on diff between HFileContext and
 HFileInfo.
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileContextBuilder.java
 Add CellComparator

M hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileWriterImpl.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreFileWriter.java
 Remove comparator caching. Get from context instead.

M hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/FixedFileTrailer.java
 Skip a reflection if we can.

M hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileInfo.java
 Javadoc. Removed unused filed.
