[dynarmic] Remove last FPT LUT table, removing around 30kb worth of unused functions (#3718 )

Lets do the quick math
There was 1 LUT for every fsize() instancing

Now... the number of functions on each lut was (fsize + 1), multiplied by 5 (number of rounding modes)

8 = 9 * 5 = 45
16 = 17 * 5 = 85
32 = 33 * 5 = 165
64 = 65 * 5 = 325

this is just pure insanity - look at what fucking nm reported:

```
0000000003dc39b8 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<16ul, false>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
0000000003dc3a18 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<16ul, true>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
0000000003dc39d8 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<32ul, false>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
0000000003dc3a38 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<32ul, true>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
0000000003dc39f8 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<64ul, false>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
0000000003dc3a58 0000000000000008 V guard variable for void Dynarmic::Backend::X64::EmitFPVectorToFixed<64ul, true>(Dynarmic::Backend::X64::BlockOfCode&, Dynarmic::Backend::X64::EmitContext&, Dynarmic::IR::Inst*)::lut
```

"ah its not bad" - OH MATE ITS JUST THE GUARD VARIABLES - i attached a file with just the functions generated for each case...

now with this PR only 6 * 6 functions are made (still not ideal, but way better), 36 is way better than 1156 FUCKING FUNCTIONS
