plat-stm32mp1: conf: restore generic default heap size

Remove reduced default heap size configuration of 48kB when pager is
enabled on stm32mp1 platforms. 48kB of core heap may not always be enough
to pass OP-TEE Test regression test 4011 related to Bleichenbacher attack
since it consumes 4.5kB more memory on in OP-TEE core since we upgraded
to Mbed TLS library 3.6.0. The platform now default uses the generic 64kB
default heap size set from mk/config.mk.

core: riscv: Improve the trap handler

In current RISC-V trap handler, we always save the context into struct
thread_trap_regs first, and copy the saved context into another specific
structure to handle that trap. For example, thread_user_ecall_handler()
copies the struct thread_trap_regs to be struct thread_scall_regs before
handling this system call. In fact, such copies may drop the performance
and they should be eliminated.

In this commit, the specific data structure used to save the context is
determined early in the trap handler by checking the type of the trap
from CSR XCAUSE. Thus, the copies between context structures are
eliminated.

core/scmi: export sub.mk files in SCP-firmware

In order to ease the update of makefile when C or Header files of
SCP-firmware project changes, we integrate them in the optee subdirectory
of SCP-firmware.

sub-optee-fvp.mk and sub-optee-stm32mp1.mk are moved unchanged in their
product directories of SCP-repository.

scmi-server/sub.mk is split:
- macro and compilation flags stay in optee-os
- srcs and incdirs are moved in product/optee directory

All modules and products related to optee are located in the
product/optee directory in the SCP-firmware repository, adding an "optee-"
prefix in the product name is useless. Remove it.

the ci will temporary point to the sha1 of the merged MR branch of
SCP-firmware. This will be replaced with next SCP-firmware tag v2.15.0
once released.
