docs: clarify build environment prerequisites

Our build system extensively uses syntax and tools that are not natively
supported by Windows shells (i.e., CMD.exe and Powershell). This
dependency necessitates a UNIX-compatible build environment. This commit
updates the prerequisites section in our documentation to reflect this.

feat(build): redirect stdin to nul during toolchain detection

It's common for Makefiles to use variables like CC, AS or LD instead of
hardcoding the name of binaries. These can be defined by the user to
use a differnet toolchain or even as a crutch to enable cross-compilation.

In TF-A, this is not needed, as support for cross-compilation is baked
in via the CROSS_COMPILE option. TF-A still defined AS for its internal
use, but unlike most other projects, the default was setting it to the C
compiler. Overriding it wasn't possible from the environment though,
only as a make argument, so this didn't cause much issue.

With commit cc277de81692 ("build: refactor toolchain detection"), AS can
now also be set from the environment. This breaks any scripts that
supply make with a cross environment that sets AS to an assembler.

Doing so was without effect before, but now leads to a quite ugly failure
mode: As TF-A now tries to detect the toolchain, it will call AS with the
option -v, which for GNU as(1) prints the version, but doesn't exit.

Thus, as(1) will continue waiting on stdin input and the build hangs
without much indication what's wrong.

Avoid this failure mode by ensuring any tool that attempts to read stdin
during toolchain detection will immediately get EOF and exit, leading to
an error message later on instead of the build hang.

fix(handoff): correct representation of tag_id

The tag ID is a 3-byte field used to identify the contents of a TE. In
our library, the internal representation of the tag is a 2 byte field.
We currently ignore the top byte of this field, marking it res0. This
causes problems when dealing with non-standard TE types, whose range
starts at 0xff_f000. This commit fixes this by using a bit-field with a
24-bit width, and packing `transfer_list_entry`.

fix(pmu): fix breakage on ARMv7 CPUs with SP_min as BL32

While comments introduced with the original commit claim that
pmuv3_disable_el3()/pmuv3_init_el3() are compatible with PMUv2 and
PMUv1, this is not true in practice: The function accesses the Secure
Debug Control Register (SDCR), which only available to ARMv8 CPUs.

ARMv8 CPUs executing in AArch32 mode would thus be able to disable
their PMUv3, while ARMv7 CPUs would hang trying to access the SDCR.

Fix this by only doing PMUv3 handling when we know a PMUv3 to be
available. This resolves boot hanging on all STM32MP15 platforms
that use SP_min as BL32 instead of OP-TEE.
