Enable Custom Key in Web SOL for Intel platform

Add customKeyEnable and KeyType items in config.json to enable
VT100+ Custom Key for Web SOL. Intel BIOS use VT100+ protocol for
console redirection, with current xtermjs key extensions, some
important keys such as Backspace, F1-F12 cannot work in Web SOL
on Intel platform in BIOS setup page and UEFI shell. To support
key extensions in VT100+, add some entries in config.json to
enable VT100+ support in Intel platforms.
