[C API] Add relaxed SIMD operations (#5482)

Exposes the constants

**Unary**

* BinaryenRelaxedTruncSVecF32x4ToVecI32x4
* BinaryenRelaxedTruncSVecF32x4ToVecI32x4
* BinaryenRelaxedTruncZeroSVecF64x2ToVecI32x4
* BinaryenRelaxedTruncZeroUVecF64x2ToVecI32x4

**Binary**

* BinaryenRelaxedSwizzleVecI8x16
* BinaryenRelaxedMinVecF32x4
* BinaryenRelaxedMaxVecF32x4
* BinaryenRelaxedMinVecF64x2
* BinaryenRelaxedMaxVecF64x2
* BinaryenRelaxedQ15MulrSVecI16x8
* BinaryenDotI8x16I7x16SToVecI16x8

**SIMDTernary**

* BinaryenRelaxedFmaVecF32x4
* BinaryenRelaxedFmsVecF32x4
* BinaryenRelaxedFmaVecF64x2
* BinaryenRelaxedFmsVecF64x2
* BinaryenLaneselectI8x16
* BinaryenLaneselectI16x8
* BinaryenLaneselectI32x4
* BinaryenLaneselectI64x2
* BinaryenDotI8x16I7x16AddSToVecI32x4

so the respective instructions can be produced and inspected with the C API.
