Summary: This diff adds new performance API `memory`, which is a read-only property that gets the current JS heap size from native side. Note that the JSI API returns an unordered map with unknown list of memory information, which is different from the [web spec](https://fburl.com/p0vpbt33). We may enforce specific memory info type on the JSI API so that it can be properly translate to the web spec. - Update the JS spec - Update Native implementation and return memory information with JSI API `jsi::instrumentation()::getHeapInfo()` - Add native performance module to catalyst package Changelog: [General][Added] - Add performance memory API with native memory Info Reviewed By: rubennorte Differential Revision: D43137071 fbshipit-source-id: 319f1a6ba78fce61e665b00849ecf2579094af83
