databases/mysql84-{server|client}: Update to 8.4.8

Bugs Fixed

InnoDB: Under certain circumstances, when using the que_eval_sql

interface, a race condition could occur. (Bug #118705, Bug #38310595)

Running SET PERSIST on a system variable after an upgrade can result

in duplicate variable entries across different sections in
mysqld-auto.cnf. (Bug #38680162)

Binary log purged before persisted binlog_expire_* options were

loaded. (Bug #38554467)

When 2 of 6 instances in a geographically dispersed InnoDB Cluster

lost connectivity, the primary server became unresponsive, causing the
COMMIT and INSERT operations to become unresponsive as well. (Bug

mysqldump's --order-by-primary option sorted data by every index on

the table, instead of just sorting by the primary key. (Bug #38284832)

Fixed several issues relating to Thread Pool blocking connections

from closing. (Bug #38170188, Bug #36782728, Bug #38549372)

GTID gaps were generated because of the replica- skip-errors option.

(Bug #28590993)

If server was started on Windows platforms with --skip-grant-tables,

privileges were not checked and remote connections were not permitted.
As a result, the server might not start. (Bug #118805, Bug #38328780)
