feat(sptool): align SP uuids to byte words

The FF-A manifest UUIDs are parsed in a function to generate the
fragment for the tb fconf dts file.

The UUID must have exactly 4 little endian words so that the the regex
in the get_uuid function can convert into canonical format. This patch
adds an assertion to catch any malformed UUID.

Moreover, the bytes.fromhex() helper expects even number of bytes.
It is possible that the hex string representing the little endian
word could have odd number of characters. For example, 0x29a has 3
characters.

This patch improves the get_uuid function to inserts 0s to the left of
the parsed value (translating `29a` to `029a`), to make sure the
bytes.fromhex can create an array of 4 integers.

This change translates any implicit pattern rules into the equivalent

refactor(build): avoid implicit pattern rules

This change translates any implicit pattern rules into the equivalent
static pattern rules, i.e. rules like:

%.o: %.s
...

... become:

$(OBJS): %.o: %.s
...

These behave similarly, but have some subtle differences. The former
defines a rule "for any target matching %.o where there is not a more
specific rule", whereas the latter defines a rule "for these targets,
which match %.o".

Where possible it is better to use a static pattern rule as it reduces
the rule space that Make needs to search.

fix(sptool): handle load-address-relative-offset property

If the SP manifest contains load-address-relative-offset then the script
failed to generate the sp_list_fragment.dts file because that line was
also added to the load_address_lines list.
This commit fixes this issue: a line is only added to the list if the
property name is exactly "load-address", without a following '-'
character.

feat(sptool): add StMM memory region descriptor

StandaloneMM partition requires that the first memory region in its list
of reserved memory regions describe the full partition layout. Hafnium
SPMC checks that memory regions in FF-A manifest do not overlap.
Therefore, this region is added directly in HOB generation code rather
than as a memory region in the FF-A manifest for the StMM partition.

build: remove Windows compatibility layer

For a couple of releases now we have officially withdrawn support for
building TF-A on Windows using the native environment, relying instead
on POSIX emulation layers like MSYS2, Mingw64, Cygwin or WSL.

This change removes the remainder of the OS compatibility layer
entirely, and migrates the build system over to explicitly relying on a
POSIX environment.

build: determine toolchain tools dynamically

Since the introduction of the toolchain detection framework into the
build system, we have done determination and identification of the
toolchain(s) used for the build at the initialization of the build
system.

This incurs a large cost to the build every time - for every toolchain
that has been requested by the current makefile, we try to identify each
tool in the list of known tool classes, even if that tool doesn't
actually see any use.

For the clean and check-like targets we worked around this by disabling
most of the toolchains if we detect these targets, but this is
inflexible and not very reliable, and it still means that when building
normal targets we are incurring that cost for all tools whether they are
used or not.

This change instead modifies the toolchain detection framework to only
initialize a tool for a given toolchain when it is first used. This does
mean that we can no longer warn about an incorrectly-configured
toolchain at the beginning of build system invocation, but it has the
advantage of substantially reducing build time and the complexity of
*using* the framework (at the cost of an increase in complexity in the
framework itself).
