Issue #18570: Add new PreferJavadocInlineTagsCheck

[vivek-0509]

Issue #18570:
Adds a new Javadoc check PreferJavadocInlineTags that enforces the use of Javadoc inline tags over their HTML equivalents, as recommended by OpenJDK Style Guidelines v6.

What does this check flag?

• <code>...</code> -> {@code ...}
• <a href="#..."> (internal links) -> {@link ...}
• &lt; -> {@literal <}
• > -> {@literal >}

What is NOT flagged (skipped)?

• Block-level HTML tags with no Javadoc equivalent: <p>, <pre>, <ul>, <li>, <table>, etc.
• External URLs: <a href="https://...">
• Content inside <pre> blocks
• Content inside {@code} and {@literal} inline tags

Should I also send a supplemental PR to sevntu.checkstyle to fix the violation caused by this new check???
