MDEV-35304: Add Connects_Tried and Master_Retry_Count to SSS

Browse Source 
When the IO thread (re)connect to a primary,
no updates are available besides unique errors that cause the failure.
These new `Master_info` numbers supplement SHOW SLAVE STATUS’s (most-
recent) ‘Connecting’ state with statistics on (re)connect attempts:

* `Connects_Tried`: how many retries have been attempted so far
  This was previously a local variable that only counted re-attempts;
  it’s now meaningful even after the “Connecting” state concludes.
* `Master_Retry_Count` (from MDEV-25674): out of how many configured

Side-note: Some of the tests updated by this commit dump the entire
SHOW SLAVE STATUS, which might include non-deterministic entries.
