Alan Agius 146d2ee246 refactor(compiler): replace flatten and map with flatMap. (#48378)
Replace custom `flatten` and `map` with native `flatMap` usage.

Benchmark:
| Test case name 	| Result                                                 	|
|----------------	|--------------------------------------------------------	|
| flatten & map  	| flatten & map x 1,182 ops/sec ±2.18% (63 runs sampled) 	|
| flatMap        	| flatMap x 6,011 ops/sec ±0.91% (35 runs sampled)       	|

The fact that `flatMap` is faster is also highlighted in https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/flatMap
