MIPS64: Fix2 '[runtime] Introduce FastNewStrictArgumentsStub to optimize strict arguments.'

Port 09d845354742a90fc0596262eb5cbaac169e5ed9

More fix after 3b980234c8d4574360fd894d69b9b1850ef0db98

Original commit message:
The FastNewStrictArgumentsStub is very similar to the recently added
FastNewRestParameterStub, it's actually almost a copy of it, except that
it doesn't have the fast case we have for the empty rest parameter. This
patch improves strict arguments in TurboFan and fullcodegen by up to 10x
compared to the previous version.

Also introduce proper JSSloppyArgumentsObject and JSStrictArgumentsObject
for the in-object properties instead of having them as constants in the
Heap class.

Drive-by-fix: Use this stub and the FastNewRestParameterStub in the
interpreter to avoid the runtime call overhead for strict arguments
and rest parameter creation.
