Adjusts the date pipe and formatDate function to detect suspicious usages of the week-numbering year formatter without including the week number, as this is often confused for the calendar year and likely to result in incorrect results near New Years, meaning that those issues aren't typically caught during development. This commit starts throwing a development-only error to reveal this issue right away.
BREAKING CHANGE:
Using the `Y` formatter (week-numbering year) without also including `w` (week number) is now detected as suspicious date pattern, as `y` is typically intended.

ISO 8601 defines
* Monday as the first day of the week.
* week 01 is the week with the first Thursday
Therefore:
Sunday Dec 31st 2023 is the last day of the last week of the year : W52 2023.

This commit adds support for Finnish full date formatting,
as well as `c/cc/ccc/cccc/ccccc/cccccc` date formats in the `DatePipe`.

In b6cd38ff05 we fixed the DatePipe so
that when it parsed date strings that looked like `YYYY-MM` it created a UTC
date that was not affected by the local timezone of the JavaScript engine.
This commit does the same for date strings of the form `YYYY`.
(Note that the previous commit, mentioned above, attempted to fix this case
too but the test was not actually checking the correct input string.)

When formatting a time with the `b` or `B` format codes, the rendered
string was not correctly handling day periods that spanned midnight.
Instead the logic was falling back to the default case of `AM`.
Now the logic has been updated so that it matches times that are within
a day period that spans midnight, so it will now render the correct
output, such as `at night` in the case of English.
Applications that are using either `formatDate()` or `DatePipe` and any
of the `b` or `B` format codes will be affected by this change.

To limit the exposure of the private `LOCALE_DATA` from outside
`@angular/core` this commit exposes private functions in the core
to hide the internal structures better.
* The `registerLocaleData()` implementation has moved from
`@angular/common` to `@angular/core`. A stub that delegates to
core has been left in common for backward compatibility.
* A new `ɵunregisterLocaleData()` function has been provided,
which is particularly useful in tests to clear out registered locales
to prevent subsequent tests from being affected.
* A private export of `ɵregisterLocaleData()` has been removed
from `@angular/common`. This was not being used and is accessible
via `@angular/core` anyway.

In `BrowserModule` the value of `LOCALE_ID` is defined in the `APPLICATION_MODULE_PROVIDERS` after `APP_INITIALIZER` has run.
This PR ensures that `LOCALE_ID` is also set for ivy at the same moment which allows the application to fetch the locale from a backend (for example).
