The `mainNgcc()` function has been refactored to make it easier to call ngcc from JavaScript, rather than via the command line. For example, the `yargs` argument parsing and the exception handling/logging have moved to the `main-ngcc.ts` file so that it is only used for the command line version. FW-1118 PR Close #29092
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
