Eric Holk (eholk) bb60967e36 [wasm] Refactor trap handlers to make way for Windows support 
In preparing for adding trap-based bounds checking to Windows, this
change refactors the code to separate the platform-specific portions
from that which can be shared between platforms.

Internally, we've renamed `RegisterDefaultSignalHandler` to
`RegisterDefaultTrapHandler` to more accurately represent the
difference in terminology between Linux (signals) and Windows
(exceptions). The external API is left the same so as not to break
downstream clients.

This CL is primarily to make room for Windows support. Future CLs
will begin adding support for Windows.

This is a reincarnation of https://crrev.com/c/626558.
