Module bytecode should use different MIME type, to avoid mixing up script/module
bytecodes for single JS file.
This patch adds a static method that simply returns the current bytecode MIME
type.
The later patch adds a new MIME type for module bytecode and modify the
ScriptLoader::BytecodeMimeTypeFor method to return corresponding MIME type.

mScript field is used only for bytecode encoding, and this field is used as a
flag for whether the script load request has bytecode-encoding-related
references.

This patch changes the way we parse JavaScript coming from Necko while loading
web pages, by adding an about:config flag named
javascript.options.delazification.strategy which is used to select between:
0 - On Demand
1 - Concurrent Depth First
255 - Parse Everything Eagerly
Previously, we moved from On-demand delazification, to parsing everything
eagerly to improve responsiveness of the browser, but we knew that more room for
optimization exists.
This toogle is meant to explore the space of delazification strategies, such
that we can parse functions of JavaScript files on an helper thread, while the
JavaScript file is being executed on the main thread. The space of
delazification strategies goes from ordering the order in which functions are
processed, as well as filtering functions which are processed. Not all functions
have to be delazified, and if the main thread needs a function which is not
parsed yet, it will fallback to parsing it on-demand.
