  1. Add Thread Local Storage (TLS) support using Picolibc functions 

    This patch provides definitions of the general TLS support macros in
terms of the Picolibc TLS support functions.

Picolibc is normally configured to use TLS internally for all
variables that are intended to be task-local, so these changes are
necessary for picolibc to work correctly with FreeRTOS.

The picolibc helper functions rely on elements within the linker
script to arrange the TLS data in memory and define some symbols.
Applications wanting to use this mechanism will need changes in their
linker script when migrating to picolibc.
