fix(cpus): workaround for Cortex-X4 erratum 2701112

Cortex-X4 erratum 2701112 is cat B erratum that applies to
revision r0p0 and is fixed in r0p1. This erratum affects
system configurations that do not use an Arm interconnect IP.

The workaround for this erratum is not implemented in EL3.
The erratum can be enabled/disabled on a platform level.
The flag is used when the errata ABI feature is enabled and can
assist the Kernel in the process of mitigation of the erratum.

fix(cpus): add erratum 2701951 to Cortex-X3's list

Erratum ID 2701951 is an erratum that could affect platforms that
do not use an Arm interconnect IP. This was originally added to the list
of Cortex-A715 in the errata ABI files.
Fixed this by adding it to the Cortex-X3 list.

refactor(errata-abi): workaround platforms non-arm interconnect

The workarounds for these below mentioned errata are not implemented
in EL3, but the flags can be enabled/disabled at a platform level
based on arm/non-arm interconnect IP flag. The ABI helps assist the
Kernel in the process of mitigation for the following errata:

Cortex-A715: erratum 2701951
Neoverse V2: erratum 2719103
Cortex-A710: erratum 2701952
Cortex-X2: erratum 2701952
Neoverse N2: erratum 2728475
Neoverse V1: erratum 2701953

feat(fvp): enable errata management interface

Errata ABI feature specific build flag, flag to enable
CPUs in the cpu list, flags to test non-arm interconnect based
errata flags when enabled from a platform level.
Added to the FVP platform makefile to test the errata abi feature
implementation.

The flags to enable CPUs in the cpu list will be removed once
synchronized with the errata framework.
