@graalvm

A few changes to #VMOptionsExplorer:
Improved JDK coverage and updated @graalvm to 21.3.0 which drops support for JDK8 in CE.

VM intrinsics information has been split out into a new #VMIntrinsicsExplorer page which now adds the "type" field (library or bytecode) and explains the flags. Also fixes parsing of the long signatures on vector intrinsics. chriswhocodes.com/vm-intrinsics-…

New page #GCExplorer lists which collectors are available in each JDK. I'm going to add information about each collector and the switches that control them. chriswhocodes.com/gc-explorer.ht… /cc @gunnarmorling @brunoborges
