Support `toolbarColor`

[aeharding]

@capacitor/browser has toolbarColor. This is nice so you can set the color so it matches your app's theme. I would really like it to also be supported in @capacitor/inappbrowser

Thanks for the great plugin!

I would also like this feature, so I took a look at the code of OSInAppBrowserLib-Android, which this package relies on. While the library itself doesn’t directly support custom modifications, the CustomTabsIntent.Builder does provide options for modifying colors, but these are marked as deprecated:

For example:

• setToolbarColor
• setNavigationBarColor
• setNavigationBarColor
• setSecondaryToolbarColor

They aren't really deprecated, they've just been moved from CustomTabsIntent.Builder to CustomTabColorSchemeParams.

CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabColorSchemeParams.Builder params = new CustomTabColorSchemeParams.Builder();

if (toolbarColor != null && !toolbarColor.isEmpty()) {
    params.setToolbarColor(Color.parseColor(toolbarColor));
}

CustomTabColorSchemeParams builtParams = params.build();

builder.setDefaultColorSchemeParams(builtParams);
builder.setColorSchemeParams(CustomTabsIntent.COLOR_SCHEME_DARK, builtParams);
