x64: Lower fcvt_from_uint in ISLE (#4684)

Browse Source 
* Add a test for the existing behavior of fcvt_from_unit

* Migrate the I8, I16, I32 cases of fcvt_from_uint

* Implement the I64 case of fcvt_from_uint

* Add a test for the existing behavior of fcvt_from_uint.f64x2

* Migrate fcvt_from_uint.f64x2 to ISLE

* Lower the last case of `fcvt_from_uint`

* Add a test for `fcvt_from_uint`

* Finish lowering fcmp_from_uint
