va: vpp: fix a wrong caps logic in vpp_transform_caps().

The current gst_va_vpp_transform_caps return such as:
  video/x-raw(memory:VAMemory), width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ],
  interlace-mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA,
  BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw(memory:DMABuf), width=(int)[ 16,
  16384 ], height=(int)[ 16, 16384 ], interlace-mode=(string)progressive, format=(string)
  { NV12, I420, YV12, YUY2, RGBA, BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw,
  width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ], interlace-mode=(string)progressive,
  format=(string){ VUYA, GRAY8, NV12, NV21, YUY2, UYVY, YV12, I420, P010_10LE };
  video/x-raw(memory:VAMemory), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ],
  interlace-mode=(string)progressive; video/x-raw(memory:DMABuf), width=(int)[ 1, 2147483647 ],
  height=(int)[ 1, 2147483647 ], interlace-mode=(string)progressive; video/x-raw, width=(int)
  [ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], interlace-mode=(string)progressive

Which is not correct. It mixes the template caps and the input query caps together.
The correct way should be: clip the template caps with the input caps(remove format
and rangify size). The correct answer should be:
  video/x-raw(memory:VAMemory), width=(int)[ 16, 16384 ], height=(int)[ 16, 16384 ], interlace
  -mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA, BGRA, P010_10LE,
  ARGB, ABGR, VUYA }; video/x-raw(memory:DMABuf), width=(int)[ 16, 16384 ], height=(int)[ 16,
  16384 ], interlace-mode=(string)progressive, format=(string){ NV12, I420, YV12, YUY2, RGBA,
  BGRA, P010_10LE, ARGB, ABGR, VUYA }; video/x-raw, width=(int)[ 16, 16384 ], height=(int)[ 16,
  16384 ], interlace-mode=(string)progressive, format=(string){ VUYA, GRAY8, NV12, NV21, YUY2,
  UYVY, YV12, I420, P010_10LE }
