Fix some relocation type issues in windows (#574)

Browse Source 
Implement Windows PE file relocation type IMAGE_REL_AMD64_ADDR64/ADDR32/REL32, implement relocation for symbol "__xmm@xxx"/"__plt@xxx"/".rdata", implement Windows invokeNative simd asm code and enable SIMD by default for windows platform. Also update wamrc tool.
