IMPALA-12465: Unicode column name support

Impala depends on Hive functions for column name
validation and uses validateName() function for the same.
Since Hive already supports unicode column names,
the patch just updates the column name validation function
to validateColumnName(). validateName() checks for a certain
conformance based on pattern matching standards while
validateColumnName() places no restrictions on column names
at the Metadata level.
This is just a primitive patch which will need a lot of testing
and enhancements as we proceed.
