ldelf: enable ubsan support

Ubsan support was previously limited to core code. This commit moves the
ubsan runtime implementation to libutils, making it available for ldelf
and trusted applications.

As a result, ldelf will now be built with ubsan support when
CFG_CORE_SANITIZE_UNDEFINED is enabled.

Additionally, to avoid potential infinite recursion, ubsan
instrumentation is explicitly disabled for ubsan.c.

build: ldelf and TAs can rely on CFLAGS32/CFLAGS64

Defines arch-bits-$(sm) for ldelf and intree TAs sub components
so that they can build using CFLAGS32 (or CFLAGS64) directives
possibly passed by the build environment.

Defines arch-bits-ta_arm32 (resp. 64) in TA devkit to leverage
CFLAGS32 (reps. CFLAGS64) directive passed by the build process. This
change is needed for external package willing to pass specific
directive to TA build sequence as toolchain's sysroot path.

Adds an inline comment describing $(sm) value in the in tree TAs build
instructions.

Add user mode ELF loader

Adds ldelf which loads user mode TAs while in user mode. The TA ELF file is
loaded and relocated by ldelf before the TA can be executed.
