Build: Update build configs to enable RAM FS on MUSCA B1 and STM
TF-M configs ITS_RAM_FS & PS_RAM_FS is now controlled by header file.
The one in CMake does not work any more. This patch uses two TF-M
patches to update the RAM FS settings in TF-M for MUSCA B1 and STM32.
This patch also enable OTP_NV_COUNTERS_RAM_EMULATION for MUSCA B1, to
avoid MCUBOOT using flash when doing OTP.
