IEP-1786 Make update site self-contained with includeAllDependencies

[sigmaaa]

Description

After deleting the p2 folder and retesting the lightweight online update site, I noticed an issue when updating from older versions that I haven't been able to resolve yet. However, we still need a reliable and robust update site that is easy to maintain and can handle updates from older IDE versions. Therefore, I decided to move the offline update site approach from this PR: #1474 into this one.

Fixes # (IEP-1786)

📝 Walkthrough

Walkthrough

The P2 update site configuration is restructured: category.xml removes the com.espressif.idf.dependencies category along with its feature/bundle entries, introduces a new com.espressif.idf.platform category containing three core Eclipse platform features, and updates category definitions. pom.xml adds a Tycho tycho-p2-repository-plugin build block with includeAllDependencies=true.

Changes

P2 Update Site Restructure

Layer / File(s)	Summary
category.xml: new platform features and category definitions releng/com.espressif.idf.update/category.xml	Removes all prior <feature> and <bundle> entries under com.espressif.idf and com.espressif.idf.dependencies. Adds org.eclipse.rcp, org.eclipse.platform, and org.eclipse.equinox.p2.user.ui features under the new com.espressif.idf.platform category. Replaces the com.espressif.idf.dependencies category-def with a new com.espressif.idf.platform category-def and trims the com.espressif.idf category-def.
pom.xml: Tycho build with includeAllDependencies releng/com.espressif.idf.update/pom.xml	Adds a <build> section configuring org.eclipse.tycho:tycho-p2-repository-plugin with includeAllDependencies=true to pull all transitive dependencies into the generated p2 repository.

Poem

🐇 Hop hop, the old dependencies are gone,
A platform category now carries on,
org.eclipse.rcp joins the dance,
includeAllDependencies — take a chance!
The update site hops neatly into place. 🌿

@sigmaaa hi !
LGTM 👍

Approach seems to be fine and helpful from the code maintenance point of view but we need to make sure it won't introduce any regressions.

Approach seems to be fine and helpful from the code maintenance point of view but we need to make sure it won't introduce any regressions.

I updated IDE v3.1.0 to v4.3.0 using the update site generated by this PR. No issues or regressions were found.
I then updated IDE v4.1.0 to v4.3.0. Again, no issues or regressions were found.

I think this is enough since this PR does not cover offline update.
