There were three options being made available to users of the linker:
- ` enableI18nLegacyMessageIdFormat`
- `i18nNormalizeLineEndingsInICUs`
- ` i18nUseExternalIds`
None of these should actually be configurable at linking time
because partially-linked libraries have tighter restrictions on
what i18n options can be used.
This commit removes those options from the `LinkerOptions` interface.
It was considered to add a check for backwards compatibilty to ensure
that if these options were being passed, and were different to the expected
defaults, we would throw an informative error. But from looking at the
Angular CLI (the only known client of the linker) it has never been setting
these options so they have already always been set to the defaults.
BREAKING CHANGE:
Linked libraries no longer generate legacy i18n message ids. Any downstream
application that provides translations for these messages, will need to
migrate their message ids using the `localize-migrate` command line tool.

This commit changes the `PartialComponentLinker` to use the original source
of an external template when compiling, if available, to ensure that the
source-mapping of the final linked code is accurate.
If the linker is given a file-system and logger, then it will attempt
to compute the original source of external templates so that the final
linked code references the correct template source.

The linker is implemented using a Babel transform such that Babel needs
to parse and walk a source file to find the declarations that need to be
compiled. If it can be determined that a source file is known not to
contain any declarations the parsing and walking can be skipped as a
performance improvement. This commit adds an exposed function for tools
that integrate the linker to use to allow short-circuiting of the linker
transform.

This commit allows compliance test-cases to be written that specify
source-map mappings between the source and generated code.
To check a mapping, add a `// SOURCE:` comment to the end of a line:
```
<generated code> // SOURCE: "<source-url>" <source code>
```
The generated code will still be checked, stripped of the `// SOURCE` comment,
as normal by the `expectEmit()` helper.
In addition, the source-map segments are checked to ensure that there is a
mapping from `<generated code>` to `<source code>` found in the file at
`<source-url>`.
Note:
* The source-url should be absolute, with the directory containing the
TEST_CASES.json file assumed to be `/`.
* Whitespace is important and will be included when comparing the segments.
* There is a single space character between each part of the line.
* Newlines within a mapping must be escaped since the mapping and comment
must all appear on a single line of this file.

Previously one could set a flag in a `TEST_CASES.json` file to exclude
the test-cases from being run if the input files were being compiled
partially and then linked.
There are also scenarios where one might want to exclude test-cases
from "full compile" mode test runs.
This commit changes the compliance test tooling to support a new
property `compilationModeFilter`, which is an array containing one or
more of `"full compile"` and `"linked compile"`. Only the tests
whose `compilationModeFilter` array contains the current compilation
mode will be run.

This commit provides the machinery for the new file-based compliance test
approach for i18n tests, and migrates the i18n tests to this new format.

ngtsc has a robust suite of testing utilities, designed for in-memory
testing of a TypeScript compiler. Previously these utilities lived in the
`test` directory for the compiler-cli package.
This commit moves those utilities to an `ngtsc/testing` package, enabling
them to be depended on separately and opening the door for using them from
the upcoming language server testing infrastructure.
As part of this refactoring, the `fake_core` package (a lightweight API
replacement for @angular/core) is expanded to include functionality needed
for Language Service test use cases.

This commit adds bazel rules to test whether linking the golden partial
files for test cases produces the same output as a full compile of the
test case would.
