Now that `ReadonlyFileSystem` and `PathManipulation` interfaces are
available, this commit updates the compiler-cli to use these more
focussed interfaces.

Now, if a source-mapping compliance test fails, the message displays both
the path to the generated file, and more helpfully the path to the expected
file.

This commit replaces `bazel` with `yarn bazel` in the error message (that instructs to regenerate golden file)
thrown while executing compliance tests. We use `yarn bazel` in other places (so we use the local version of bazel,
not the global one).
PR Close#40078
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 this would have just printed that `false` was not equal to
`true`, which, although true, is not very helpful. This commit adds
details about which special check failed together with the generated
code, for easier debugging.

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.

This commit contains the basic runner logic and a couple of sample test cases
for the "full compile" compliance tests, where source files are compiled
to full definitions and checked against expectations.
