CryptoPkg/OpensslLib: Drop dependency on ArmSoftFloatLib
Drop the ArmSoftFloatLib dependency from the OpensslLib implementations,
so that we can retire this git submodule and associated dependencies in
other components.
The upshot of this is that OpenSSL can no longer be used on 32-bit ARM
by components that rely on the random number generation routines (which
is where the floating point usage resides). In practice, this means that
ARM platforms should use MbedTLs instead for things like signed
capsules, authenticated variables and TPM2 support. HTTPS boot is no
longer supported, as TlsDxe depends on OpensslLib directly.
Note that MbedTLS itself -surprisingly- depends on OpensslLib as well,
but only for the SM3 routines, and incorporating those does not require
softfloat support.

RedfishPkg: Drop ARM support
Redfish uses JsonLib, which supports encoding real numbers. This
handling is implemented using C floating point types, which means that
on 32-bit ARM, a softfloat library is required, even though the CPUs we
still (marginally) care about all support floating point in hardware.
The UEFI spec does not permit the use of floating point on ARM at all,
and so the correct thing to do here is to simply disable this driver on
32-bit ARM entirely.
Note that the ARM platform code does allow the VFP unit to be enabled at
boot time, and so rebuilding this driver with hardware FP should be
feasible, in case anyone has an interest in running it on a 32-bit ARM
system.

SignedCapsulePkg: Drop ARM support
ARM requires softfloat routines when incorporating OpenSSL, which is a
bit of a hassle for no benefit, given that ARM is mostly obsolete at
this point.
SignedCapsulePkg relies on OpenSSL for authentication, and while it
might be feasible to migrate ARM to MbedTLS and retain support, let's
just drop support entirely.
