https://bugs.webkit.org/show_bug.cgi?id=171138

Rubber-stamped by Chris Dumez.

Extracted CustomConfigurationTestGroupForm out of CreateAnalysisTaskPage and added it to AnalysisTaskPage inside
AnalysisTaskConfiguratorPane. This allows configuration of a new test group within a custom analysis task.

* public/privileged-api/create-test-group.php:
(main): Fixed the bug that the triggerable wasn't resolved when creating a test group in a custom analysis task.

* public/v3/components/custom-analysis-task-configurator.js:
(CustomAnalysisTaskConfigurator.prototype.selectTests): Added. Used by CustomConfigurationTestGroupForm's
setConfigurations.
(CustomAnalysisTaskConfigurator.prototype.selectPlatform): Ditto.
(CustomAnalysisTaskConfigurator.prototype.setCommitSets): Ditto.
(CustomAnalysisTaskConfigurator.prototype._setUploadedFilesIfEmpty): Added.
(CustomAnalysisTaskConfigurator.prototype._revisionMapFromCommitSet): Added.
(CustomAnalysisTaskConfigurator.prototype.render): Update the currently selected platforms and tests now that
they can be set externally via selectTests and selectPlatform.
(CustomAnalysisTaskConfigurator.prototype._renderTriggerableTests): Return the result of _renderRadioButtonList
so that the caller can update the currently selected tests without having to reconstruct the list.
(CustomAnalysisTaskConfigurator.prototype._renderTriggerablePlatforms): Ditto.
(CustomAnalysisTaskConfigurator.prototype._renderRadioButtonList): Renamed from _buildCheckboxList. Now returns
a function which updates the currently selected items. We still pretend that multiple items can be selected to
make it future-proof.

* public/v3/components/custom-configuration-test-group-form.js: Added.
(CustomConfigurationTestGroupForm): Added. Inherits from TestGroupForm. Extracted from CreateAnalysisTaskPage.
(CustomConfigurationTestGroupForm.prototype.setHasTask): Added.
(CustomConfigurationTestGroupForm.prototype.hasCommitSets): Added.
(CustomConfigurationTestGroupForm.prototype.setConfigurations): Added. Used by AnalysisTaskConfiguratorPane to
set the default configuration to what the latest test group used.
(CustomConfigurationTestGroupForm.prototype.startTesting): Added. Dispatches "startTesting" action with
platform, test, taskName in addition to what CustomizedTestGroupForm emits.
(CustomConfigurationTestGroupForm.prototype.didConstructShadowTree): Added.
(CustomConfigurationTestGroupForm.prototype.render): Added.
(CustomConfigurationTestGroupForm.prototype._updateTestGroupName): Added.
(CustomConfigurationTestGroupForm.cssTemplate): Added.
(CustomConfigurationTestGroupForm.htmlTemplate): Added.

* public/v3/components/test-group-form.js:
(TestGroupForm.cssTemplate): Make the form display: block.

* public/v3/index.html:

* public/v3/models/test-group.js:
(TestGroup.prototype.test): Added.
(TestGroup.prototype.platform): Added.
(TestGroup.createWithCustomConfiguration): Added. Creates a custom test group with an existing analysis task.

* public/v3/models/uploaded-file.js:
(UploadedFile): Fixed a bug that _deletedAt was set to a Date object even when object.deletedAt is null.

* public/v3/pages/analysis-task-page.js:
(AnalysisTaskConfiguratorPane): Added.
(AnalysisTaskConfiguratorPane.prototype.didConstructShadowTree): Added. Dispatch createCustomTestGroup action
in turn when receiving startTesting from CustomConfigurationTestGroupForm.
(AnalysisTaskConfiguratorPane.prototype.setTestGroups): Added.
(AnalysisTaskConfiguratorPane.prototype.render): Added.
(AnalysisTaskConfiguratorPane.htmlTemplate): Added. We override this instead of formContent to display the
"Start" button at the end instead of at the beginnning.
(AnalysisTaskConfiguratorPane.cssTemplate): Added.
(AnalysisTaskPage.prototype.didConstructShadowTree): Listen to createCustomTestGroup.
(AnalysisTaskPage.prototype.render): Hide AnalysisTaskConfiguratorPane when the analysis task is not custom.
(AnalysisTaskPage.prototype._showTestGroup): Let AnalysisTaskConfiguratorPane know of the current test group
so that it can update the default configuration if the user hasn't modified yet.
(AnalysisTaskPage.prototype._createCustomTestGroup): Added.

* public/v3/pages/create-analysis-task-page.js:
(CreateAnalysisTaskPage.prototype.didConstructShadowTree):

(MockData.addMockData): Added a test configuration for otherPlatformId.
