Ahmed Ismail 4d0a28d269 armv8-m: Do not overwrite Control register value 
The current ARMv8-M FreeRTOS-Kernel Port code
implementation is modified in a way that allows
the CONTROL register's value to be retained
rather than being overwritten.

This is needed for adding PACBTI support as
the special-purpose CONTROL register `PAC_EN`,
`UPAC_EN`, `BTI_EN`, and `UBTI_EN` PACBTI
enablement bits should be configured before calling
`vRestoreContextOfFirstTask()` function which currently
overwrite the value inside the CONTROL register.
