Currently Ivy stores the element attributes into an array above the component def and passes it into the relevant instructions, however the problem is that upon minification the array will get a unique name which won't compress very well. These changes move the attributes array into the component def and pass in the index into the instructions instead.
Before:
```
const _c0 = ['foo', 'bar'];
SomeComp.ngComponentDef = defineComponent({
template: function() {
element(0, 'div', _c0);
}
});
```
After:
```
SomeComp.ngComponentDef = defineComponent({
consts: [['foo', 'bar']],
template: function() {
element(0, 'div', 0);
}
});
```
A couple of cases that this PR doesn't handle:
* Template references are still in a separate array.
* i18n attributes are still in a separate array.

Accessing a string's character at index allocates a new, single character string.
A better (faster) check is to use `charCodeAt` that doesn't trigger allocation.
This simple change speeds up the element_text_create benchmark by ~7%.

The history_server rule is not longer shipped with rules_nodejs as it has been replaced by auto-generated rule `load("@npm//history-server:index.bzl", "history_server")` which requires the user to add history-server to their package.json.

The components repository updated to rules_nodejs#0.38.0 before Angular Bazel did.
To do this, the `@angular/bazel` v0.38.0 compatibility changes were patched on postinstall.
This now conflicts because we install a `@angular/bazel` version in the `material-unit-tests` job
that already includes these compatibility changes. This would result in the patch being a noop
for which the `patch` command throws an error.
We can remove this once components can install a released version of `@angular/bazel` that is
compatible with `rules_nodejs#0.38.0`.

Currently the `ngForOf` input accepts `null` or `undefined` as valid
values. Although when using strict template input type checking
(which will be supported by `ngtsc`), passing `null` or `undefined`
with strict null checks enabled causes a type check failure because
the type for the `ngForOf` input becomes too strict if strict null checks
are enabled. The type of the input needs to be expanded to also accept
`null` or `undefined` to behave consistently regardless of the
`strictNullChecks` flag.
This is necessary because whenever strict input type checking is enabled
by default, most of the Angular projects that use `*ngFor` with the async pipe
will either need to disable template type checking or strict null checks
because the `async` pipe returns `null` if the observable hasn't been
emitted yet.
See for example how this affects the `angular/components` repository and
how much bloat the workaround involves: https://github.com/angular/components/pull/16373/files#r296942696.

In View Engine, animation metadata could occur in nested arrays which
would be flattened in the compiler. When compiling a component for Ivy
however, the compiler no longer statically evaluates a component's
animation metadata and is therefore unable to flatten it statically.
This resulted in an issue to find animations at runtime, as the metadata
was incorrectly registered with the animation engine.
Although it would be possible to statically evaluate the animation
metadata in ngtsc, doing so would prevent reusable animations exported
from libraries from being usable as ngtsc's partial evaluator is unable
to read values inside libraries. This is unlike ngc's usage of static
symbols represented in a library's `.metadata.json`, which explains how
the View Engine compiler is able to flatten the animation metadata
statically.
As an alternative solution, the metadata flattening is now done in the
runtime during the registration of the animation metadata with the
animation engine.

As mentioned in the previous commit, the regexp used by
`Validators.email()` is a slightly enhanced version of the
[WHATWG one](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address).
This commit refactors the regexp (without changing its behavior) to make
it more closely match the format of WHATWG version, so that it is easier
for people to compare it against the WHATWG one and understand the
differences.
The main changes were:
- Changing the order of characters/character classes inside `[...]`;
e.g. `[A-Za-z]` --> `[a-zA-Z]`
- Mark all groups as non-capturing (since we do not use the captured
values); e.g. `(foo)` --> `(?:foo)`
(This could theoretically also have a positive performance impact, but
I suspect JavaScript engines are already optimizing away capturing
groups when they are not used.)
PR Close#32961
Previously, there was no documentation of what `Validators.email()`
expects as a valid e-mail address, making it difficult for people to
determine whether it covers their requirements or not. Even more so that
the used pattern slightly deviates from the
[WHATWG version](https://html.spec.whatwg.org/multipage/input.html#valid-e-mail-address).
One's only option was to look at the source code and try to decipher the
regexp pattern.
This commit adds a high-level description of the validator and mentions
its similarity to and differences from the WHATWG version. It also adds
a brief explanation of the regexp's behavior and references for more
information in the source code to provide more context to
maintainers/users trying to understand the implementation in the future.

Prior to this commit, the `ng` was exposed in global namespace, which turned out to be problematic when minifying code with Closure, since it sometimes clobber our `ng` global.

The `init_environment` custom command is used in almost all other jobs.
The this is implemented in CircleCI is that the steps of the command are
inlined into the other jobs.
Some of the `init_environment` commands are quite long and (since the
default display name for a step is its command) they clutter the
CircleCI UI. Additionally, multiple related commands are shown as
separate steps, which makes it more difficult to get to the actual steps
of a job.
This commit improves this by:
1. Defining explicit, short names for steps with long commands.
2. Grouping multiple related steps into one.

This commit removes the `enabledIvy: false` configuration, thus allowing

SyntaxError: invalid syntax

It seems expected, because `print` is not a function, so
`print(foo, *args)` is interpreted as printing a tuple (where `*args` is
invalid syntax). Not sure why it doesn't break on other people's
machines :/
This change makes the verbose logs a little less pretty, but that
shouldn't be a big issue (given that it is an opt-in feature and it can
always be overwritten locally, if necessary).

The creation of StaticReflector in createMetadataResolver() is a very expensive operation because it involves numerous module resolutions.
To make matter worse, since the API of the Reflector does not provide the ability to invalidate its internal caches, it has to be destroyed and recreated on *every* program change.
This has a HUGE impact on performance.
This PR fixes this problem by carefully invalidating all StaticSymbols in a file that has changed, thereby reducing the overhead of recomputation on program change.
