Drop the JVM "feature" concept support

...now that 6ba74150866d71469827de9f4f19268dfa7db137
"jfw::isAccessibilitySupportDesired is obsolete" demonstrated that there is no
more need for JFW_FEATURE_ACCESSBRIDGE, the sole feature that had been provided.

* The javasettings_*.xml format still supports the <feature> tag, but it is
ignored when reading and always written as "0".

* There is no trace that "the bootstrap parameter
JFW_PLUGIN_NO_NOT_CHECK_ACCESSIBILITY" whose mention gets removed from
jvmfwk/plugins/sunmajor/pluginlib/JREProperties.java had ever been supported.
(The only mention was 6873b3be47d71f94c38262003101576081acd241 "INTEGRATION:
CWS jre5issues (1.3.18); FILE MERGED: 2005/01/18 12:48:48 jl 1.3.18.1:
#i40879# in build environment the JRE is not tested for accessibility, because
of potential X server problems" introducing that comment.)

* The "Features" column is removed from the JRE table on the "LibreOffice -
Advance" options page.

-    When support for assistive technology is required, then the
