Restore cross-BDA injection fallback for WAR inside EAR

TOMEE-4600 removed the openejb.cache.cdi-type-resolution-failure feature and,
as collateral, also deleted WebAppInjectionResolver and its installation in
WebappBeanManager. That resolver's fallback allowed a WAR's BeanManager to
resolve beans declared in its parent EAR's library jars, which OWB's stock
InjectionResolver does not do. Without it, CdiParentBeanTest fails with
UnsatisfiedResolutionException for @Inject references from WAR code to
EAR-lib CDI beans.

Reintroduce a minimal WebAppInjectionResolver that only contains the
cross-BDA fallback (the cache-resolution-failure infrastructure stays
removed) and reinstall it from the WebappBeanManager constructor.
