Rework 'MOVE ALL' to 'ALTER .. ALL IN TABLESPACE'

As 'ALTER TABLESPACE .. MOVE ALL' really didn't change the tablespace
but instead changed objects inside tablespaces, it made sense to
rework the syntax and supporting functions to operate under the
'ALTER (TABLE|INDEX|MATERIALIZED VIEW)' syntax and to be in
tablecmds.c.

Pointed out by Alvaro, who also suggested the new syntax.

Back-patch to 9.4.

<para>
This form changes the index's tablespace to the specified tablespace and
moves the data file(s) associated with the index to the new tablespace.
To change the tablespace of an index, you must own the index and have
<literal>CREATE</literal> privilege on the new tablespace.
All indexes in the current database in a tablespace can be moved by using
the <literal>ALL IN TABLESPACE</literal> form, which will lock all
indexes to be moved and then move each one. This form also supports
<literal>OWNED BY</literal>, which will only move indexes owned by the
roles specified. If the <literal>NOWAIT</literal> option is specified
then the command will fail if it is unable to acquire all of the locks
required immediately. Note that system catalogs will not be moved by
this command, use <command>ALTER DATABASE</command> or explicit
<command>ALTER INDEX</command> invocations instead if desired.
