Make PHP 7.3 the primary PHP version on Travis CI

Replaced MockPlatform with the ones generated by PHPUnit

Fixed a typo in PoolingShardConnection phpdoc

Replaced Xdebug with PCOV for code coverage

Marked some test classes abstract

1. SchemaManagerFunctionalTestCase can be run only via an extending class. Otherwise, it skips all tests. If the test case is represented as an abstract class, PhpStorm will offer a choise of concrete classes which is very handy when debugging test failures.
2. DbalFunctionalTestCase and DbalPerformanceTestCase are meant to be used as base classes and don't contain any tests.

Replaced MySQL 5.7 installed from a PPA with an official Docker image

See https://travis-ci.org/doctrine/dbal/jobs/495144274 for the PPA issue.

CI: Test against PHP 7.4snapshot instead of nightly (8.0)

Fixed AppVeyor build configuration and the issue on SQL Server

PowerShell doesn't automatically handle exit codes of the invoked commands automatically, and $ErrorActionPreference = "Stop" doesn't seem working. Additionally, the ocular command is moved out of the "test_script" section to "after_test" since it's not part of the actual test.
