Remove org.osgi.service.http and felix.http.servlet-api from SDK TP

[HannesWell]

With eclipse-equinox/equinox#403 the sources of org.osgi.service.http are provided in a re-packed bundle from Equinox, that also provides the OSGi capabilities which where temporarily provided by felix.http.servlet-api.

As planned, this also reverts #1672 because it is not necessary anymore.

Build is green and looking at the build's console output I can see no [WARNING] Problems resolving provisioning plan regarding the osgi packages or bundles. So this is good to go.

@HannesWell Would you please adjust javadocs build ? They are broken now https://download.eclipse.org/eclipse/downloads/drops4/I20231218-1800/compilelogs/platform.doc.isv.javadoc.txt . If/when #1533 is finished failing javadocs should fail the build so issues like this one should be uncovered earlier.

@HannesWell I suspect that the platform build now fails de to these changes as well:
https://ci.eclipse.org/platform/job/eclipse.platform/job/master/

it complains about

Failed to execute goal org.eclipse.tycho:tycho-p2-director-plugin:4.0.5-SNAPSHOT:materialize-products (create-distributions) on project infocenter-product: Installation of product infocenter for environment linux/gtk/x86_64 failed

I think this is more an issue of the replacement of embedded sources itself, but I'm not entirely sure.
Created eclipse-platform/eclipse.platform#1054, which at least fixed my local build (without tests).
