 Build/Test Tools: Configure Xdebug modes in the local Docker environment.

 One change in the update from Xdebug version 2.x to 3.x was a shift from
 enabling features to switching into modes.

 When the version of Xdebug installed in the PHP 7.4 Docker container was
 updated from 2.x to 3.x, the code coverage reporting workflow stopped
 generating reports due to a lack of available coverage drivers.

 This change adds the `XDEBUG_MODE` environment variable to the local
 Docker environment configuration to allow the active modes to be changed.
 This environment variable takes precedence over the `xdebug.mode` setting,
 but will not change the value of the `xdebug.mode` setting.

 The `LOCAL_PHP_XDEBUG_MODE` environment variable has been added to the
 `.env` file and can be used to change the modes enabled in the Docker
 container. The code coverage reporting workflow uses this variable to
 enable the `coverage` mode, which is required for generating a test
 coverage report.

 By default, `debug` and `debug modes are active, which enables the more
 commonly used features of Xdebug: development helpers and step debugging.

 Props afragen, johnbillion, desrosj.
 Fixes #56022.
