[AND-243] Save attachments on attachment picker dismiss

[VelikovPetar]

🎯 Goal

Add an additional configuration flag to AttachmentsPickerTheme(compose) and AttachmentsPickerDialogStyle(xml): saveAttachmentsOnDismiss which configures the whether the selected attachments should be 'saved' and added to the composer, if the user dismisses the picker. The idea is to prevent the 'loss' of attachments, if a user accidentally dismisses the picker after selecting one or more attachments. (Defaults to false, to persist the current default behaviour, where the selected attachments are dismissed if the picker is dismissed)

🛠 Implementation details

• Add saveAttachmentsOnDismiss flag in AttachmentsPickerTheme(compose)
• Add saveAttachmentsOnDismiss flag in AttachmentsPickerDialogStyle(xml)
• If the flag is set to false, ensure the selected attachments are propagated to the composer after dismissing the picker

Usage

Compose:

ChatTheme(
        attachmentPickerTheme = AttachmentPickerTheme.defaultTheme(colors).copy(
              saveAttachmentsOnDismiss = true,
        ),
        // ...
) {
      // ...
}

XML:

<io.getstream.chat.android.ui.feature.messages.composer.MessageComposerView
        android:id="@+id/messageComposerView"
        app:streamUiMessageComposerAttachmentsPickerSaveAttachmentsOnDismiss="true"
        />
