[3.0] org.eclipse.persistence.jpa.jse.test test fixes against Oracle DB - backport from master

[rfelcman]

This PR contains fixes for following test errors if JPA JSE tests are executed against Oracle DB:

1. org.eclipse.persistence.jpa.embeddable.TestCollectionTableEmbeddable

[ERROR] Tests run: 2, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 2.281 s <<< FAILURE! - in org.eclipse.persistence.jpa.embeddable.TestCollectionTableEmbeddable
[ERROR] org.eclipse.persistence.jpa.embeddable.TestCollectionTableEmbeddable.mergeTest  Time elapsed: 0.325 s  <<< ERROR!
org.eclipse.persistence.exceptions.ConversionException: 

Exception Description: The object [04-DEC-21 03.56.45.937000000 AM], of class [class java.lang.String], from mapping [org.eclipse.persistence.mappings.DirectToFieldMapping[temporalValue-->EntMapDateTemporal.TEMPORALVALUE]] with descriptor [RelationalDescriptor(org.eclipse.persistence.jpa.embeddable.model.ElementCollectionEmbeddableTemporal --> [DatabaseTable(EntMapDateTemporal)])], could not be converted to [class java.sql.Timestamp].
	at org.eclipse.persistence.jpa.embeddable.TestCollectionTableEmbeddable.mergeTest(TestCollectionTableEmbeddable.java:73)

In entity org.eclipse.persistence.jpa.embeddable.model.ElementCollectionEmbeddableTemporal is specified DB column type. Without this is VARCHAR2 used. VARCHAR2 is problematic in case of read operation (conversion) back into java.util.Date.

2. org.eclipse.persistence.jpa.test.lob.TestLobMerge

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.646 s <<< FAILURE! - in org.eclipse.persistence.jpa.test.lob.TestLobMerge
[ERROR] org.eclipse.persistence.jpa.test.lob.TestLobMerge.testLobMerge  Time elapsed: 1.543 s  <<< ERROR!
jakarta.persistence.RollbackException: 
Exception [EclipseLink-4002] (Eclipse Persistence Services - 4.0.0.v202112030849): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CLOB

Error Code: 932
Call: DELETE FROM ParentEntity_SUBS WHERE (((content = ?) AND (label = ?)) AND (parent_id = ?))
	bind => [3 parameters bound]
Query: DeleteObjectQuery(org.eclipse.persistence.jpa.test.lob.model.CollectedEntity@9bffba99)
	at org.eclipse.persistence.jpa.test.lob.TestLobMerge.testLobMerge(TestLobMerge.java:78)
Caused by: org.eclipse.persistence.exceptions.DatabaseException: 

Internal Exception: java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected - got CLOB

It leads into EclipseLink fix in some *Platform classes, org.eclipse.persistence.internal.descriptors.ObjectBuilder and org.eclipse.persistence.mappings.foundation.AbstractDirectMapping.

3. org.eclipse.persistence.jpa.test.mapping.TestMultitenantOneToMany

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.106 s <<< FAILURE! - in org.eclipse.persistence.jpa.test.mapping.TestMultitenantOneToMany

jakarta.persistence.PersistenceException: 
Exception [EclipseLink-4002] (Eclipse Persistence Services - 4.0.0.v202112070752): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLSyntaxErrorException: ORA-02420: missing schema authorization clause

Error Code: 2420
Call: CREATE SCHEMA tenant_1

	at org.eclipse.persistence.jpa.test.mapping.TestMultitenantOneToMany.setup(TestMultitenantOneToMany.java:59)
Caused by: org.eclipse.persistence.exceptions.DatabaseException: 

Internal Exception: java.sql.SQLSyntaxErrorException: ORA-02420: missing schema authorization clause

Test change to use prefix based multitenancy.
