Generate new vocabulary POJOs

[berezovskyi]

Description

Adds generation for modern vocabulary POJOs, including:

• a URI constant for every RDFS class
• a URI constant for every RDFS property
• an efficient QName helper method every RDFS property
• Javadoc with the RDFS class/property description for every constant and QName helper
• @Deprecated annotation for constants and QName helpers that are marked with a description "archaic"

Additional changes:

• delete the Matlab domain
• fix the oscl prefix
• fix the git attributes for MTL files to end with an LF line terminator to prevent issues for Git repos with autocrlf setting on.
• add only slf4j-api for non-servlet (domain) project POMs.
• address a compilation warning in the adaptors due to deprecated new Boolean(string) calls by switching to Boolean.valueOf(string)
• Fix bad license ident BSD-3-Clause not BSD-3-Simple

Pull request overview

This PR modernizes the vocabulary POJO generation to create cleaner, more efficient code with improved documentation and caching mechanisms for QName objects.

Key Changes:

• Generates modern vocabulary classes with URI constants for RDFS classes and properties, QName helper methods, and comprehensive Javadoc
• Refactors slf4j dependencies to use only slf4j-api for domain projects, moving slf4j-simple to servlet-specific dependencies
• Fixes deprecated new Boolean() constructor usage in favor of Boolean.valueOf()

@berezovskyi What do you think of hte suggested changes.
I regenerated on eclipse-lyo/lyo#848 as well.

i have not changed the file names yet.
to better trace changes (at least for my mind), I think it better to do another PR for file name changes. such a commit simply shows filename changes (and associated code changes), but nothing else.

@Jad-el-khoury Looks good.

One comment: can we get rid of the local names? Or, at least, remove local name concatenation outside the vocab class? For example, eclipse-lyo/lyo@f6384ce#diff-d9fe2502a3e88924c68ec001d4ab09f1832174c0a15e207984574b1f3a2950beR96 should not have

@OslcPropertyDefinition(DctermsVocabularyConstants.NS + "title")

but

@OslcPropertyDefinition(DctermsVocabularyConstants.TITLE_PROP)

Minor nit: can we add a newline before the javadoc start to avoid props and javadocs being squished all together? Just a cosmetic thing.
