The commit cfa34d9 ("Add support for compiling in-tree TAs") added
spec-srcs and spec-out-dir for special handling of user_ta_header.c when
compiling in-tree TAs.

However, these variables are just as relevant for out-of-tree TAs
compiled via ta/mk/ta_dev_kit.mk. So as a simplification switch to use
spec-srcs and spec-out-dir in that file too.

Introduce two new variables srcs_ext-y and srcs_ext_base-y to deal with
compiling source code outside of this git (optee_os.git).

srcs_ext_base-y assigns the root directory of the external source files
to compile. srcs_ext-y works as srcs-y except that it's relative to the
$(srcs_ext_base-y) directory.

Introduce the per source file variable oname-<file name>-y to override
the default output object file name. This helps to shorten and make a
more sane name for the output object file name when the source file is
outside optee_os source tree, for instance, a third-party library.

_plat__Fail() is declared with a __noreturn since it's guaranteed to not
