Valentin Shergin a4cc519a52 Fabric: Synthetic benchmarks for prop parsing infra 
Summary:
And, btw, the tests show that performance of that is not so great:
```
Running /Users/shergin/fbsource/fbobjc/buck-out/cells/fbsource/gen/xplat/js/react-native-github/ReactCommon/fabric/core/benchmarks
Run on (12 X 2900 MHz CPU s)
CPU Caches:
  L1 Data 32K (x6)
  L1 Instruction 32K (x6)
  L2 Unified 262K (x6)
  L3 Unified 12582K (x1)
--------------------------------------------------------------------------------------------
Benchmark                                                     Time           CPU Iterations
--------------------------------------------------------------------------------------------
propParsingUsingComponentDescriptor                       79630 ns      77991 ns       8864
propParsingUsingComponentDescriptorWithNoSourceProps      70200 ns      69099 ns       8362
```

Which means 70ms per 1000 prop parsing processes.
