MDEV-15705 Remove global status counter Innodb_pages0_read

Browse Source 
MDEV-9931 introduced a counter for keeping track of reads of the
first page of InnoDB data files, because the original implementation
of data-at-rest-encryption for InnoDB introduced new code paths for
reading the pages.

Ultimately, the extra reads of the first page were removed, and
the encryption subsystem will be initialized whenever we first read
the first page of each data file, in fil_node_open_file(). It should not
be that interesting to observe how many times an InnoDB data file was
opened for the first time.
