Webpack and other build tools sometimes inline the contents of the source files in their generated source-maps, and at the same time change the paths to be prefixed with a protocol, such as `webpack://`. This can confuse tools that need to read these paths, so now it is possible to provide a mapping to where these files originated. PR Close #32912
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.
