Mark APIs as unsupported on Browser WASM

[MaximLipnin]

We can use UnsupportedOSPlatformAttribute("browser") attribute to mark unsupported APIs on Browser WASM so that the analyzer can provide warnings when developers accidentally call platform-specific APIs.
Spec: dotnet/designs#144

We use the scanner (https://github.com/dotnet/platform-compat) to gather the list of all the APIs throwing PNSE on Browser WASM at the moment. Below is the file containing ~4500 PNSE methods.
pnse-17082020.txt

There can be some special cases:

• APIs can be Windows-specific
• APIs might throw PNSE for all platforms
• APIs might not be considered to be marked (e.g. APIs are not meant to be directly called by user code)
• other cases?

area-VM-meta-mono seems like the wrong area for this since it's purely libraries, but I'm not sure what to use for something that applies to libraries as a whole. area-Meta also seems wrong...
