MDEV-32841 Add tests for new counters.

Only add innodb_async_reads/writes_total_count here.
For all other counters, writing reproducible tests is rather tricky.

MDEV-32841 Provide Innodb async IO statistics

Provide some statistics about asynchronous IO reads and writes:
- number of pending operations
- number of completion callbacks that are currently being executed
- number of completion callbacks that are currently queued
(due to restriction on number of IO threads)
- total number of IOs finished
- total time to wait for free IO slot
- total number of completions that were queued.

Also revert tpool InnoDB perfschema instrumentation (MDEV-31048)
That instrumentation of cache mutex did not bring any revelation (
the mutex is taken for a couple of instructions), and made it impossible
to use tpool outside of the server (e.g in mariadbimport/dump)

MDEV-28152 Features for sequences

- Add `as <int_type>` to sequence creation options
  - int_type can be signed or unsigned integer types, including
    tinyint, smallint, mediumint, int and bigint
  - Limitation: when alter sequence as <new_int_type>, cannot have any
    other alter options in the same statement
  - Limitation: increment remains signed longlong, and the hidden
    constraint (cache_size x abs(increment) < longlong_max) stays for
    unsigned types. This means for bigint unsigned, neither
    abs(increment) nor (cache_size x abs(increment)) can be between
    longlong_max and ulonglong_max
- Truncating maxvalue and minvalue from user input to the nearest max
  or min value of the type, plus or minus 1. When the truncation
  happens, a warning is emitted
- Information schema table for sequences
