Some platforms don't format a variable store template at build time; instead they format the non-volatile varstore flash chip during boot, dynamically. Introduce NvVarStoreFormattedLib to enable such platforms to delay the "variable read" service drivers until the platform specific module(s) report that the variable store has been formatted. The platform-specific module that performs the formatting during startup is usually an FVB or MM FVB driver. Under the proposed scheme, it becomes responsible for installing gEdkiiNvVarStoreFormattedGuid with a NULL interface in the protocol database. In turn, the platform DSC will hook NvVarStoreFormattedLib into the variable service driver, to make the latter wait for the FVB driver. Platforms that need not delay the variable service driver like this may still use the same FVB driver; gEdkiiNvVarStoreFormattedGuid will simply be ignored.
