Add toMatchInlineSnapshot support (#55892)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55892

Adds `toMatchInlineSnapshot()` to the Fantom custom `expect` implementation,
matching Jest's inline snapshot behavior. On first run, snapshot values are
written directly into the test source file as template literal arguments.
On subsequent runs, values are compared and the test fails on mismatch
unless the `-u` flag is passed to force an update.

The implementation spans the two-process Fantom architecture:

**Runtime (Hermes VM):**
- `snapshotContext.js`: New `toMatchInlineSnapshot` method that compares
  received values against existing inline snapshots, captures stack traces
  for new/mismatched snapshots, and tracks results per test.
- `expect.js`: New `toMatchInlineSnapshot` method on the `Expect` class
  that serializes values with `prettyFormat` and delegates to snapshot context.
- `setup.js`: Plumbs `inlineSnapshotResults` through `TestCaseResult`.

**Runner (Node.js):**
- `snapshotUtils.js`: New `processInlineSnapshotResults` resolves VM stack
  traces back to original source locations via source map symbolication.
  New `saveInlineSnapshotsToSource` directly rewrites the test source file
  by finding each `toMatchInlineSnapshot(...)` call and replacing its
  argument with the formatted template literal. This avoids jest-snapshot's
  `saveInlineSnapshots` which requires Babel and Prettier 2.x.
- `runner.js`: Generates source maps when inline snapshots need updating,
  collects pending snapshots across test configs, and writes them after
  all configs complete.
