Andrew Kushnir 6cff877f4f perf(core): make DI decorators tree-shakable when used for `useFactory` deps config (#40145)
This commit updates the logic that calculates `useFactory` function arguments to avoid relying on `instanceof`
checks (thus always retaining symbols) and relies on flags that DI decorators contain (as a monkey-patched property).

Another perf benefit is having less megamorphic reads while calculating args for the `useFactory` call: we used to
check whether a token has `ngMetadataName` property 4 times (in worst case), now we have just 1 megamorphic read in
all cases.

Closes #40143.
