Blobs: introduce EFR32xG27 BLE/RAIL binary blobs

[fkokosinski]

Origin

This is a follow up to #54865 and #57181.

Three binary blobs are to be introduced:

• libbluetooth_controller_efr32xg27_gcc_release.a
• libbgcommon_efr32xg27_gcc_release.a
• librail_efr32xg27_gcc_release.a

The origin of these binary blobs is the Silicon Labs Gecko SDK repository: https://github.com/SiliconLabs/gecko_sdk.

Type

• [x] Precompiled library
• [ ] Firmware image

Module

hal_silabs: https://github.com/zephyrproject-rtos/hal_silabs/.

Purpose

Precompiled static libraries (binary blobs) supporting EFR32 RF subsystems in EFR32xG27-based boards.
