WFLY-1370 Allow CDI Extension to be loaded from static modules
This commit changes the way CDI portable extensions are loaded,
so they will be picked up from any module that has its services
exposed to the deployment.

This will both allow users to register portable extensions from
static modules, and also allow subsystems to more easily register
extensions.

[WFLY-1385] Override page-size-bytes default value

The max-size-bytes parameter default value (-1) is overridden in
messaging subsystem configuration to BLOCK at 10MiB.
If the admin changes the address-full-policy from BLOCK to PAGE, this
will conflict with the default value for page-size-bytes (10MiB) which
*must* be smaller than max-size-bytes.
=> override it to 2MiB to avoid any issues when the queues are paging
(and it has no incidence when the queues are blocking)
