[Backport][PVR][GUI] 'Next recording on ...' label time is not localized

[djp952]

Description

Backport of PR #19551 for Matrix branch

The "Next recording on..." label shown in the PVR Timers and PVR Timer Rules view does not localize the time portion of the label correctly:

Motivation and Context

After a time consuming "deep" search, this concern has apparently existed since PVR was first implemented in Frodo via PR #1357. I searched the current PVR implementation and did not find any additional instances where the localized date/time format is being ignored, and do not have any other suggested edits to resolve.

How Has This Been Tested?

Tested on Kodi master branch current as of 2021.04.09, on Windows x64 (Desktop), with:

• Settings / Interface / Regional / Regional default format -> USA (12h)
• Settings / Interface / Regional / Time format --> Regional (h:mm:ss xx)

Screenshots (if appropriate):

Before the requested change, the time portion of the label shows as HH:mm on all platforms and regions:

After the requested change the time portion of the label is localized based on Settings as expected:
