Feature: #107105 - Introduce expression for accessing site locale

See forge#107105

Description

A new Symfony ExpressionLanguage expression locale() has been introduced.

This expression allows integrators and developers to directly access the current site locale, which is provided as a locale object. All public methods of this object are available for use.

Have a look at the corresponding documentation for more details: API

Example

[locale().getName() == "en-US"]
    page.20.value = bar
[END]
[locale().getCountryCode() == "US"]
    page.30.value = foo
[END]
[locale().isRightToLeftLanguageDirection()]
    page.40.value = bar
[END]
Copied! 
variants:
  -
    identifier: language-variant-1
    condition: 'locale().getName() == "en-US"'
    label: 'First name'
Copied!

Impact

Developers can now easily compare the locale of the current site directly in expression contexts, without the need for using siteLanguage("locale").
