Currently the decorator handlers are run against all `SourceFile`s in the compilation, but we shouldn't be doing it against declaration files. This initially came up as a CI issue in #33264 where it was worked around only for the `DirectiveDecoratorHandler`. These changes move the logic into the `TraitCompiler` and `DecorationAnalyzer` so that it applies to all of the handlers.

For the purposes of the integration test the zone.js script & bundle script tags can just go into the source index.html itself. The purpose of the integration test is is to test @angular/bazel & ng_module & ng_package so there is no need to exercise html_insert_assets in integration/bazel.

The major one that affects the angular repo is the removal of the bootstrap attribute in nodejs_binary, nodejs_test and jasmine_node_test in favor of using templated_args --node_options=--require=/path/to/script. The side-effect of this is that the bootstrap script does not get the require.resolve patches with explicitly loading the targets _loader.js file.

This commit renames `addAttributeValuesToCompletions`, which generates
expression completions and is not exclusive to processing attributes, to
`processExpressionCompletions`. Also removes the expression completion
logic in `visitBoundText` for a call to `processExpressionCompletions`.
The conditional branch in `visitBoundText` is also removed. This branch
was added in one of the first commits to the language service
(519a324454) and appears to be
unnecessary, as the expression AST is constructed from the template
position anyway.

Previously, the `CommonJsReflectionHost` and `UmdReflectionHost` would
only recognize re-exports of the form `__export(...)`. This is what
re-exports look like, when the TypeScript helpers are emitted inline
(i.e. when compiling with the default [TypeScript compiler options][1]
that include `noEmitHelpers: false` and `importHelpers: false`).
However, when compiling with `importHelpers: true` and [tslib][2] (which
is the recommended way for optimized bundles), the re-exports will look
like: `tslib_1.__exportStar(..., exports)`
These types of re-exports were previously not recognized by the
CommonJS/UMD `ReflectionHost`s and thus ignored.
This commit fixes this by ensuring both re-export formats are
recognized.

A while ago we made a pass through all instructions to make sure that none of them call directly into other instructions, however it seems like missed the `pipeBind*` since they still call into the pure functions. The result is that we have some unnecessary duplicated accesses of global state like `getLView` which are called twice in a row with nothing changing.
These changes move the common functionality into a shared file and make the pipe instructions call into them with the global state instead.

The compiler's `I18NHtmlParser` may expand template nodes that have
internationalization metadata attached to them; for instance,
```html
<div i18n="@@i18n-el">{{}}</div>
```
gets expanded to an AST with the i18n metadata extracted and text filled
in as necessary; to the language service, the template above, as read in
the AST, now looks something like
```html
<div>{{$implicit}}</div>
```
This is undesirable for the language service because we want to preserve
the original form of the source template source code, and have
information about the original values of the template. The language
service also does not need to use an i18n parser -- we don't generate
any template output.
To fix this turns out to be as easy as moving to using a raw
`HtmlParser`.
---
A note on the testing strategy: as mentioned above, we don't need to use
an i18n parser, but we don't **not** need to use one if the parser
does not heavily modify the template AST. For this reason, the tests
target the functionality of not modifying a template with i18n metadata
rather than testing that the language service does not use an i18n parser.

With 5cecd97493 we intended to expand
the input type of the `disabled` input of the `NgModel` directive.
Read more about the reason for this in the actual commit message.
Currently though, the acceptance coercion member does not have any
effect. This is because the acceptance member needs to refer to the
actual input property name, and not to the public input name.
`disabled` corresponds to the `isDisabled` property.

This commit improves `ExpressionChangedAfterChecked` error message for attributes by including attribute name and the content of the entire expression that contains interpolation(s). In order to achieve that, metadata is now stored in `TData` array when `attribute` and `attributeInterpolate` instructions are being called (similar to `property` and `propertyInterpolate` instructions).

In some cases, where a module imports a dependency
but does not actually use it, UMD bundlers may remove
the dependency parameter from the UMD factory function
definition.
For example:
```
import * as x from 'x';
import * as z from 'z';
export const y = x;
```
may result in a UMD bundle including:
```
(function (global, factory) {
typeof exports === 'object' && typeof module !== 'undefined' ?
factory(exports, require('x'), require('z')) :
typeof define === 'function' && define.amd ?
define(['exports', 'x', 'z'], factory) :
(global = global || self, factory(global.myBundle = {}, global.x));
}(this, (function (exports, x) { 'use strict';
...
})));
```
Note that while the `z` dependency is provide in the call,
the factory itself only accepts `exports` and `x` as parameters.
Previously ngcc appended new dependencies to the end of the factory
function, but this breaks in the above scenario. Now the new
dependencies are prefixed at the front of parameters/arguments
already in place.

In some cases TypeScript is unable to identify a valid
symbol for an export. In this case it returns an "unknown"
symbol, which does not reference any declarations.
This fix ensures that ngcc does not crash if such a symbol
is encountered by checking whether `symbol.declarations`
exists before accessing it.
The commit does not contain a unit test as it was not possible
to recreate a scenario that had such an "unknown" symbol in
the unit test environment. The fix has been manually checked
against that original issue; and also this check is equivalent to
similar checks elsewhere in the code, e.g.

Fixes classes with trailing or leading space that are passed to `ngClass` (e.g. `{'foo ': bar}`) not being applied in Ivy. The issue comes from the fact that when the styling differ builds up the style map it uses the trimmed key to look up the value in the map that uses non-trimmed keys.

Follow-up from [this discussion](https://github.com/angular/angular/pull/33419#discussion_r339296216). In Ivy we don't use the schema to validate tag names, but instead we use feature detection to figure out whether an element is supported. While this should generally be more accurate, it'll also end up throwing for some more innocent cases. E.g. now Ivy throws an error for `main` elements in IE which is accurate since IE doesn't support the element, but is annoying since there is no functionality attached.
These changes switch to logging a warning instead, similarly to what we're doing for unknown properties.

Previously, in cases were values were expensive to compute and would be
used multiple times, a combination of a regular `Map` and a helper
function (`getOrDefault()`) was used to ensure values were only computed
once.
This commit uses a special `Map`-like structure to compute and memoize
such expensive values without the need to a helper function.

While different, CommonJS and UMD have a lot in common regarding the
their exports are constructed. Therefore, there was some code
duplication between `CommonJsReflectionHost` and `UmdReflectionHost`.

However, it is possible in some UMD variations to have the latter format
as well. See discussion in https://github.com/angular/angular/pull/34254/files#r359515373

This fix was part of a broader `ngtsc`/`ngcc` fix in 02bab8cf9 (see

`UmdReflectionHost`. Later in #34254, the fix was partially ported to
`UmdReflectionHost` by fixing the `extractUmdReexports()` method.
This commit fully fixes `ngcc`'s handling of inline exports for code in
UMD format.

The `getProjectAsAttrValue` in `node_selector_matcher` finds the
ProjectAs marker and then additionally checks that the marker appears in
an even index of the node attributes because "attribute names are stored
at even indexes". This is true for "regular" attribute bindings but
classes, styles, bindings, templates, and i18n do not necessarily follow
this rule because there can be an uneven number of them, causing the
next "special" attribute "name" to appear at an odd index. To address
this issue, ensure ngProjectAs is placed right after "regular"
attributes.

Previously, if `UmdRenderingFormatter#addImports()` was called with an
empty list of imports to add (i.e. no new imports were needed), it would
add trailing commas in several locations (arrays, function arguments,
function parameters), thus making the code imcompatible with legacy
browsers such as IE11.
This commit fixes it by ensuring that no trailing commas are added if
`addImports()` is called with an empty list of imports.

ngcc computes a dependency graph of entry-points to ensure that
entry-points are processed in the correct order. Previously only the imports
in source files were analysed to determine the dependencies for each
entry-point.
This is not sufficient when an entry-point has a "type-only" dependency
- for example only importing an interface from another entry-point.
In this case the "type-only" import does not appear in the
source code. It only appears in the typings files. This can cause a
dependency to be missed on the entry-point.
This commit fixes this by additionally processing the imports in the
typings program, as well as the source program.
Note that these missing dependencies could cause unexpected flakes when
running ngcc in async mode on multiple processes due to the way that
ngcc caches files when they are first read from disk.
