feat(psci): make pabandon support generic

Support for aborted powerdowns does not require much dedicated code.
Rather, it is largely a matter of orchestrating things to happen in the
right order.

The only exception to this are older secure world dispatchers, which
assume that a CPU_SUSPEND call will be terminal and therefore can
clobber context. This was patched over in common code and hidden behind
a flag. This patch moves this to the dispatchers themselves.

Dispatchers that don't register svc_suspend{_finish} are unaffected.
Those that do must save the NS context before clobbering it and
restoring in only in case of a pabandon. Due to this operation being
non-trivial, this patch makes the assumption that these dispatchers will
only be present on hardware that does not support pabandon and therefore
does not add any contexting for them. In case this assumption ever
changes, asserts are added that should alert us of this change.

refactor(cm): convert el1-ctx assembly offset entries to c structure

Currently the EL1 part of the context structure (el1_sysregs_t),
is coupled with feature flags reducing the context memory allocation
for platforms, that don't enable/support all the architectural
features at once.

Similar to the el2 context optimization commit-"d6af234" this patch
further improves this section by converting the assembly context-offset
entries into a c structure. It relies on garbage collection of the
linker removing unreferenced structures from memory, as well as aiding
in readability and future maintenance. Additionally, it eliminates
the #ifs usage in 'context_mgmt.c' source file.

spd: trusty: allow clients to retrieve service UUID

This patch implements support for the 64-bit and 32-bit versions of
0xBF00FF01 SMC function ID, as documented by the SMCCC, to allow
non-secure world clients to query SPD's UUID.

In order to service this FID, the Trusty SPD now increases the range
of SMCs that it services. To restrict Trusty from receiving the extra
SMC FIDs, this patch drops any unsupported FID.

Verified with TFTF tests for UID query and internal gtest for Trusty.
