tableam: basic documentation.

Browse Source 
This adds documentation about the user oriented parts of table access
methods (i.e. the default_table_access_method GUC and the USING clause
for CREATE TABLE etc), adds a basic chapter about the table access
method interface, and adds a note to storage.sgml that it's contents
don't necessarily apply for non-builtin AMs.

This optional clause specifies the table access method to use to store
the contents for the new materialized view; the method needs be an
access method of type <literal>TABLE</literal>. See <xref
linkend="tableam"/> for more information. If this option is not
specified, the default table access method is chosen for the new
materialized view. See <xref linkend="guc-default-table-access-method"/>
for more information.
