[20732] Fix some leaks in XML DynamicTypes Parser (backport #4717)

[mergify]

Description

This PR adds a regression test with the XML reported from OSS Fuzz, and performs the following two actions on every method parsing and registering a dynamic type:

#. Doing a pre-check on whether a type with the same name is already registered in the profile manager, and perform an early return in that case
#. Tell DynamicTypeBuilderFactory to delete the builder when a call to XMLProfileManager::insertDynamicTypeByName fails.

@Mergifyio backport 2.13.x 2.10.x 2.6.x
