Module scripts should always decode using UTF-8

Reviewed by Youenn Fablet.
By default, CachedScript tries to use the best encoding when decoding script
data. However, per the specification [1], we should always decode as UTF-8 when
it is used as a module (unlike in the classic script case).
This patch adds a ShouldDecodeAsUTF8Only to CachedScript::script() and
scriptHash() and updates CachedScriptSourceProvider pass
ShouldDecodeAsUTF8Only::Yes when used for a module script.
I believe that in theory, the same CachedScript could be used both for a module
script and a classic script, which is why I implemented it this way.
