Makes machine.UART objects static instances (similar to other ports), adds machine_uart_deinit_all() function for cleanup on soft reset. - Fixes the case where the OS-level uart_event_task is leaked (along with 2KB of heap) when a UART object is garbage collected (including after a soft reset). - Fixes hard fault if a previous UART irq() fires after the UART object is garbage collected (including after a soft reset), but before any new UART object is instantiated for the same UART number. - Constructing multiple UART objects for the same UART now returns the same instance multiple times, not different instances. - Was also able to streamline deinit/init to only install the driver once, rather than install-with-defaults/uninstall/reinstall. Alternative would be to add a finaliser, but this is more consistent with how most other UART objects are implemented. This work was funded through GitHub Sponsors.
