Modules already have a separate entrypoint into the engine (at the moment,
this is v8::ScriptCompiler::CompileModule, though that will change to
something like ParseModule). This meant that requiring a commandline flag
simply added an extra complexity burden on embedders. By removing the v8
flag, this lets embedders use their own flagging mechanism (such as d8's
"--module", or Blink's RuntimeEnabledFeatures) to control whether
modules are to be used.
Also remove old modules tests that were being skipped (since they test
very old, pre-ES2015 modules syntax).

Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.
d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).
