LOG: [DirectX][ObjectYAML] Fix SRCI Names parsing on Big Endian (#202020)

```
Names.Parameters = HeaderOnDisk;
```
converts SRCI Names section header from little endian to platform native
byte order (in converting constructor).
Therefore, extra
```
  if (sys::IsBigEndianHost)
    Names.Parameters.swapBytes();
```
can swap bytes of the header fields again, causing an error on SPARC:
```
SRCI Names section content ends beyond the section boundary
```

Fix that.
