Additionally, for applying "|Meta|" to Windows Logo keys in Linux, we
need to reconsider about the legacy "meta" modifier state of Linux.
Typically, it's mapped to Alt-Shift, but we use the highest priority
modifier state of modifier keys

it's not exposed to the web within major distributions' default
settings (i.e., exposed as "|Alt|" and "|Shift|" modifiers). However,
if users customized key mapping to a modifier is pure Meta modifier
key, it may be exposed on Firefox. I'm not sure how we should treat
this. Currently, I'm think that it should be treated as "|Alt|"
because typically "meta" state is mapped to Alt key, but it's just
considered without concrete idea. So, I'm fully open about this issue.
This change is canceled because Sun/Solaris keyboard layout map it to
the Windows Logo keys
<https://phabricator.services.mozilla.com/D183480#inline-1018842>.
So, listing up my intention is:
* Change Windows Logo key |.key| values from "|OS|" to "|Meta|" in
Windows/Linux
* Change Windows Logo key |.code| values from "|OSLeft|"/"|OSRight|"
to "|MetaLeft|"/"|MetaRight|" in Windows/Linux
* Change Command key |.code| values from "|OSLeft|"/"|OSRight|" to
"|MetaLeft|"/"|MetaRight|" in macOS
* Change modifier state of Windows Logo keys from "|OS|" to "|Meta|"
in Windows/Linux (affecting both |.getModifierState()| and |.metaKey|
* Treat legacy meta key/modifier in Linux as "|Alt|" key/modifier
