lib/xlat_tables: Add support for ARMv8.4-TTST

ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the
size of translation tables by increasing the maximum permitted value
of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and
VSTCR_EL2.

This feature is supported in AArch64 state only.

This patch adds support for this feature to both versions of the
translation tables library. It also removes the static build time
checks for virtual address space size checks to runtime assertions.

Sanitise includes across codebase

Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

xlat lib: Reorganize architectural defs

Move the header files that provide translation tables architectural
definitions from the library v2 source files to the library include
directory. This allows to share these definitions between both
versions (v1 and v2) of the library.

Create a new header file that includes the AArch32 or AArch64
definitions based on the AARCH32 build flag, so that the library user
doesn't have to worry about handling it on their side.

Also repurpose some of the definitions the header files provide to
concentrate on the things that differ between AArch32 and AArch64.
As a result they now contain the following information:
- the first table level that allows block descriptors;
- the architectural limits of the virtual address space;
- the initial lookup level to cover the entire address space.

Additionally, move the XLAT_TABLE_LEVEL_MIN macro from
xlat_tables_defs.h to the AArch32/AArch64 architectural definitions.

This new organisation eliminates duplicated information in the AArch32
and AArch64 versions. It also decouples these architectural files from
any platform-specific information. Previously, they were dependent on
the address space size, which is platform-specific.

Finally, for the v2 of the library, move the compatibility code for
ADDR_SPACE_SIZE into a C file as it is not needed outside of this
file. For v1, this code hasn't been changed and stays in a header
file because it's needed by several files.
