[foreign-memaccess+abi] RFR: 8268169: The system lookup can not find stdio functions such as printf on Windows 10

[Jorn Vernee]

Hi,

This patch adds a way to look up stdio functions such as printf on Windows 10 through the system lookup. A fallback library is used which forces the generation of these inline functions, and exposes them through a table of function pointers.

Thanks,
Jorn
