libutils, zlib: fix Clang warnings

Clang 18.1.6 reports the following warnings:

CC out/arm/ldelf-lib/libutils/isoc/bget_malloc.o
In file included from lib/libutils/isoc/bget_malloc.c:127:
lib/libutils/isoc/bget.c:607:7: warning: a function definition without a prototype is deprecated in all versions of C and is not supported in C23 [-Wdeprecated-non-prototype]
607 | void *bget(requested_align, hdr_size, requested_size, poolset)
| ^

And same with lib/zlib/{adler32.c,inffast.c,inflate.c,zutil.c}.

In addition, zutil.c causes:

CC out/arm/core/lib/zlib/zutil.o
core/lib/zlib/zutil.c:28:33: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
28 | const char * ZEXPORT zlibVersion()
| ^
| void

Add -Wno-deprecated-non-prototype to libutils' bget_malloc.c to silence
the first series, and simply remove -Wstrict-prototypes (added by
default by mk/compile.mk) when building zlib.

The path to platform specific code is hard-coded. This commit
changes it to use defined variable. This is helpful in case
of porting OP-TEE OS to a new architecture such we make
maximum reuse of existing sources.

Preparing for C++ support in TAs.

Adds a few <stdio.h> functions to libutils:

The proposed implementations are limited in the sense that they only
accept writing to stdout or stderr. The output goes directly to the
secure console and no difference is made between stdout and stderr.

plat-vexpress: fix non-debug build

Fixes a number of build errors when 'PLATFORM=vexpress' and 'DEBUG=':
- '<var> may be used uninitialized'
- 'dereferencing type-punned pointer will break strict-aliasing rules'
This one is addressed by adding -fno-strict-aliasing to the cflags for the
problematic files, which is a temporary solution.
- 'inlining failed'

Also, make sure tee_svc_syscall_table is aligned on a 32-bit boundary.
Otherwise, an alignment fault might occur:
ERR [0x0] TEE-CORE:tee_pager_print_error_abort:101: data-abort at 0x602f16b

Note: on Foundation_v8, I measured a ~3x speedup between debug and non-debug
builds for asymmetric crypto tests.
