This commit adds a logic to produce a warning in case HttpClient doesn't use fetch during SSR.
It's recommended to use `fetch` for performance and compatibility reasons.

This rename reflects what the function actually does. Although the intention
is still not to have two different interceptor mechanisms, that is now
communicated in the docs for the function instead of in its name.

Ordinarily, providing `HttpClient` (either via `provideHttpClient` or the
`HttpClientModule`) creates an entirely separate HTTP context. Requests made
via that client are not passed through the interceptor chains that are
configured in a parent injector, for this example.
This commit introduces a new option for `provideHttpClient` called
`withRequestsMadeViaParent()`. When this option is passed, requests made in
the child context flow through any injectors, etc. and are then handed off
to the parent context.
This addresses a longstanding issue with interceptors where it's not
possible to extend the set of interceptors in a child context without
repeating all of the interceptors from the parent.

This commit introduces a new feature for `provideHttpClient` called
`withInterceptors`. This feature exposes and configures the new concept of
functional interceptors.
Functional interceptors use functions instead of classes to implement an
HTTP interceptor. Such interceptor functions have access to the DI context
from the `EnvironmentInjector` in which they're configured via the
`inject()` function. Otherwise, functional interceptors are identical in
capability to the existing interceptor system.

This commit introduces the main components of the `provideHttpClient()`
provider API, designed in the style of `provideRouter()`. Initial features
are defined for including legacy class-based interceptors, JSONP support,
and configuring or disabling the builtin XSRF protection.
This API is an alternative to providing `HttpClient` via the
`HttpClientModule`, and is more tree-shakable and more capable than the
NgModule implementation.
Tests are included to validate the new configuration format as well as the
interoperability of the two styles of providing and configuring
`HttpClient`.
