This commit adds a t.assert.fileSnapshot() API to the test runner.
This is similar to how snapshot tests work in core, as well as
userland options such as toMatchFileSnapshot().

This commit refactors the internals of snapshot tests to get the
name of the test file from the test context instead of passing
it to the SnapshotManager constructor. This is prep work for
supporting running test files in the test runner process.

Snapshotted values are escaped after serialization.
This happens when serializing a value for comparison
when snapshots already exist, and also when updating them.
That is, snapshots are escaped in the internal storage,
but when written to disk, one "level" of escaping is removed.
That escaping is never added back when reading the snapshots back.
This makes even the simplest test trying to serialize a string
with an escape code in it fail, like the one I added here.

This commit adds a t.assert.snapshot() method that implements
snapshot testing. Serialization uses JSON.stringify() by default,
but users can configure the serialization to meet their needs.
