[flutter_runner] use dedicated allocation info

    This informs the vulkan driver that we're allocating memory
    dedicated to a single image. This is required for aemu and
    might also allow future drivers to make optimizations currently
    not possible.

    No change in behavior. Existing tests (modular_tests,
    scenic_tests, etc.) are sufficient and regressions will be
    prevented by running these tests on aemu.

* [flutter_runner] Move from runner context to component context

* remove the file references

Build rules still reference creating share snapshot data and instructions. This makes the engine to always pass them as empty to the dart vm. To be followed up with a change to alter the build rules to stop referencing the shared snapshots.

This is not being used currently and the fact that the runner will be built outside of the flutter tree means that the apps will not have much to gain via shared snapshots. The rationale behind this change is to partially make migrating the runner out of topaz tree easier.

Change-Id: Ibc4dd6a298d65082416af753522f5a17c88a750a

New features for golden tests (for web):

* Height/width of headless browser instance extracted to constants
* Remove border from the host iframe
* Added 'region' to matchGoldenFile, so screenshots can capture only
a subset of the viewport
* Added image-format-awareness (png) to screenshot comparison, so it
doesn't only look at raw bytes
* When a test fails, output a diff image alongside the unexpected
output.

Account for root surface transformation on the surfaces managed by the external view embedder. (#11384)

The earlier design speculated that embedders could affect the same
transformations on the layers post engine compositor presentation but before
final composition.

However, the linked issue points out that this design is not suitable for use
with hardware overlay planes. When rendering to the same, to affect the
transformation before composition, embedders would have to render to an
off-screen render target and then apply the transformation before presentation.
This patch negates the need for that off-screen render pass.

To be clear, the previous architecture is still fully viable. Embedders still
have full control over layer transformations before composition. This is an
optimization for the hardware overlay planes use-case.

Fixes b/139758641

The tests we write must be resilient to the order in which they are run in the
harness. That is, they must not rely on global state set by other tests that
have already run in the process. Also, these tests must themselves be
repeatable. That is, they must correctly clean up after themselves and be able
to run successfully again in the same process.

This patch adds some safeguards against (but does NOT guarantee) the addition of
tests that violate the dictum.

Additionally, test failures must be easily reproducible for folks investigating
the test failure. Also, tests that assert correctness of unrelated code must not
stop progress on the authors patch.

This changes does not hinder reproducibility of test failures because the random
seed is printed in the logs before running each test. Developers attempting to
reproduce the failure locally can do the same via the following invocation
`--gtest_shuffle --gtest_repeat=<the count> --gtest_random_seed=<seed from failing run>`.

This change does introduce potential burden on patch authors that may see
failures in unrelated code as a newly failing shuffle seed is used on their
runs. To ameliorate this, we will formulate guidance for them to aggressively
mark such tests as disabled and file bugs to enable the same.

The test seed is intentionally kept low because it’s purpose is to test that
individual tests are repeatable. It must not be used as a replacement for
fuzzing.
