XIP adaptation for xtensa platform (#1636)

Browse Source 
Add macro WASM_ENABLE_WORD_ALING_READ to enable reading
1/2/4 and n bytes data from vram buffer, which requires 4-byte addr
alignment reading.

Eliminate XIP AOT relocations related to the below ones:
   i32_div_u, f32_min, f32_max, f32_ceil, f32_floor, f32_trunc, f32_rint
