Previously ngtsc assumed resource files (templateUrl, styleUrls) would be
physically present in the file system relative to the .ts file which
referenced them. However, ngc previously resolved such references in the
context of ts.CompilerOptions.rootDirs. Material depends on this
functionality in its build.
This commit introduces resolution of resources by leveraging the TypeScript
module resolver, ts.resolveModuleName(). This resolver is used in a way
which will never succeed, but on failure will return a list of locations
checked. This list is then filtered to obtain the correct potential
locations of the resource.

This commit adds support for resolution of styleUrls to ngtsc. Previously
this field was never read, and so components with styleUrls would appear
unstyled after compilation.

When a single resource is preloaded twice in ngtsc, the second request
would be recognized as in-flight in which case `undefined` would
be returned, which signals to the compilation that is can resume
synchronously. The compilation would then proceed immediately and call
`load`, only to find out that the request is still in-flight which is
not allowed.
This commit caches the Promise of the in-flight fetch requests, such
that subsequent preload requests can return the corresponding Promise
instance.

* Currently when building a `ng_module` with Bazel and having the flat module id option set, the flat module files are not being generated because `@angular/compiler-cli` does not properly determine the entry-point file.
Note that this logic is not necessarily specific to Bazel and the same problem can happen without Bazel if multiple TypeScript input files are specified while the `flatModuleIndex` option has been enabled.

Currently when building the `ng_package` multiple times, the old `ng_package` output will be copied over to the new `ng_package` content. Resulting in packages like `src/cdk/npm_package/npm_package/npm_package/AND_MORE`.
This happens because currently all TypeScript definition files are resolved from within the `binDir`. This is just wrong because it could then take up the `d.ts` files from the previous `ng_package` output. All typescript definitions that belong to the target package, should be resolved through Bazel and copied based on that computation.
Also fixes that `esm` files aren't written to the `ng_package` on Windows. This is because we try to flatten paths using the `path.delimiter` while the path is always using Posix delimiters (causing the paths to be incorrect)

* Currently when building the ES5 and ES2015 output, `ngc_wrapped` will fail because it tries to write the `fs.openSync` the tsickle output file at the same time. This causes a runtime exception in Windows and can be fixed by just writing the externs for ES5 mode to the proper ES5 "output root".

* Fixes that `ng_package` does not work generate UMD bundles on Windows because the `esm5/` files are not written to the output directory. This is because `rootDirs` and `rootDir` are posix paths and cause invalid relative paths when mixed with Windows backslash paths.

With this change, we no longer depend on CircleCI to trigger the webhook
(which it sometimes does with considerable delay or not at all).
This has the added benefit that other jobs will not unnecessarily
trigger webhooks and spam the preview server logs. It is only the
`aio_preview` job's webhook that we care about.

Prior to this change, the number of host vars stored for directives with `hostBindings` in expando block was incorrect for inherited directives (in case both parent and child directive have `hostBindings` defined). Now if we identify that we already added a `hostBinding` into expando block, we just increase the corresponding number of host binding vars

The problem was caused by missing `allocateBindingSlots` that led to incorrect # of vars defined for components and as a result, causing errors at runtime. Now all `bind` operation are accounted for and the number of `vars` is correct.

The problem was caused by the self-closing i18n instruction that was generated in case we have styling instructions defined for a component. As a result, that caused problems at runtime. This update adds extra check to avoid creating self-closing i18n instructions (create i18nStart and i18nEnd instructions instead) when styling instructions are present.

Ngcc will now render additional exports for classes that are referenced in
`NgModule` decorated classes, but which were not publicly exported
from an entry-point of the package.
This is important because when ngtsc compiles libraries processed by ngcc
it needs to be able to publcly access decorated classes that are referenced
by `NgModule` decorated classes in order to build templates that use these
classes.
Doing this re-exporting is not without its risks. There are chances that
the class is not exported correctly: there may already be similarly named
exports from the entry-point or the class may be being aliased. But there
is not much more we can do from the point of view of ngcc to workaround
such scenarios. Generally, packages should have been built so that this
approach works.

There are a number of variables that need to be passed around
the program, in particular to the renderers, which benefit from being
stored in well defined objects.
The new `EntryPointBundle` structure is a specific format of an entry-point
and contains the compiled `BundleProgram` objects for the source and typings,
if appropriate.
This change helps with future refactoring, where we may need to add new
properties to this object. It allows us to maintain more stable APIs between
the constituent parts of ngcc, rather than passing lots of primitive values
around throughout the program.

The `NgModuleDecoratorHandler` can now register all the references that
it finds in the `NgModule` metadata, such as `declarations`, `imports`,
`exports` etc.
This information can then be used by ngcc to work out if any of these
references are internal only and need to be manually exported from a
library's entry-point.

By inverting the relationship between `EntryPointPaths` and
`EntryPointFormat` we can have interfaces rather than types.

If a decorated class is not publicly exported via an entry-point then the
previous approach to finding the associated typings file failed.
Now we ensure that we extract all the class declarations from the
dtsTypings program, even if they are not exported from the entry-point.
This is achieved by also parsing statements of each source file, rather
than just parsing classes that are exported from the entry-point.
Because we now look at all the files, it is possible for there to be multiple
class declarations with the same local name. In this case, only the first
declaration with a given name is added to the map; subsequent classes are
ignored.
We are most interested in classes that are publicly exported from the
entry-point, so these are added to the map first, to ensure that they are
not ignored.

In Angular, it used to be an accepted practice to use strings as dependency
injection tokens. E.g. {provide: 'test', useValue: 'provided'}. However,
the Ivy node injection system did not support this. The Ivy DI system
attempts to patch a Bloom bit index onto each type registered with it, and
this patch operation does not work for a string token.
This commit adds string token support to the bloom filter system by
reserving bit 0 for string tokens. This eliminates the need for each string
token to store its own Bloom bit, at the expense of slightly more expensive
lookups of string tokens.

Having real functions allows me to bypass individual checks, ex.:
```
export function fixmeIvy(reason: string): boolean {
return true;
}
```
This is useful for situation where I want to see if previously disabled tests
were fixed (ex. some PRs merged). In this case I don't want to run tests that
I know are not passing (obsolete / modified).

BREAKING CHANGES:
Bazel users: rules_angular_dependencies() will no longer install transitive dependencies of build_bazel_rules_nodejs and build_bazel_rules_typescript. User WORKSPACE files will now need to install rules_nodejs and rules_typescript transitive deps directly:
```
load("@build_bazel_rules_typescript//:package.bzl", "rules_typescript_dependencies")
rules_typescript_dependencies()
load("@build_bazel_rules_nodejs//:package.bzl", "rules_nodejs_dependencies")
rules_nodejs_dependencies()
```
