ADMIN_MOVE_TABLE and db2look result in partition table column range definitions padding extra blank spaces when using config STRING_UNITS = CODEUNITS32

ADMIN_MOVE_TABLE and db2look need to be updated to properly support STRING_UNITS = CODEUNITS32.

When running ADMIN_MOVE_TABLE on a partitioned table with the 'MOVE' option, or when running db2look, in an environment with the db cfg setting for STRING_UNITS=CODEUNITS32, the PARTITION BY clause will pad the columns range values with trailing blank spaces, resulting in an SQL0443N error message.  For example:

CREATE TABLE "TEST_PART"  ( "SUFFIX_NBR" CHAR(4 CODEUNITS32) NOT NULL )
PARTITION BY RANGE("SUFFIX_NBR")
(PART "1" STARTING(MINVALUE) ENDING('EEEE'),
PART "2" STARTING('FFFF') ENDING(X'48484848'),
PART "3" STARTING('IIII') ENDING('~~~~'),
PART "4" STARTING(U&'\0140ód\017A') ENDING(U&'\0141ód\017A'))
ORGANIZE BY ROW

call sysproc.admin_move_table('TESTUSER','TEST_PART','','','MOVE,TRACE')

SQL0433N  Value "EEEE
" is too long.  SQLSTATE=22001

The create table stmt for the target table ends up looking like:

CREATE TABLE "TESTUSER"."TEST_PARTACBEOEt"("SUFFIX_NBR" CHARACTER(4 CODEUNITS32) NOT NULL) ORGANIZE BY ROW IN "IBMDB2SAMPLEREL" INDEX IN "IBMDB2SAMPLEREL" LONG IN "IBMDB2SAMPLEREL"
PARTITION BY RANGE("SUFFIX_NBR")
(PART "1" STARTING(MINVALUE) ENDING('EEEE            ') IN "IBMDB2SAMPLEREL" INDEX IN "IBMDB2SAMPLEREL" LONG IN "IBMDB2SAMPLEREL",
 PART "2" STARTING('FFFF            ') ENDING('HHHH            ') IN "IBMDB2SAMPLEREL" INDEX IN "IBMDB2SAMPLEREL" LONG IN "IBMDB2SAMPLEREL",
 PART "3" STARTING('IIII            ') ENDING('~~~~            ') IN "IBMDB2SAMPLEREL" INDEX IN "IBMDB2SAMPLEREL" LONG IN "IBMDB2SAMPLEREL",
 PART "4" STARTING('ŀódź         ') ENDING('Łódź         ') IN "IBMDB2SAMPLEREL" INDEX IN "IBMDB2SAMPLEREL" LONG IN "IBMDB2SAMPLEREL")

and values of length 18 for clause ENDING('EEEE            '), etc, do not fit into the column SUFFIX_NBR with a size of 4 chars.
