fix(cpus): workaround for Cortex-A725 erratum 3711914

Cortex-A725 erratum 3711914 is a Cat B erratum that applies
to revisions r0p0 and r0p1 and it is fixed in r0p2.

This erratum can be avoided by inserting a DMB LD after each DSB ST instruction.

This erratum can be avoided by setting CPUACTLR2_EL1[0] to 1. The

invalidations to other PE caches. There might be a small performance
degradation to this workaround for certain workloads that share data.

feat(cpufeat): add support for FEAT_UINJ

FEAT_UINJ allows higher ELs to inject Undefined Instruction exceptions
into lower ELs by setting SPSR_ELx.UINJ, which updates PSTATE.UINJ on
exception return. When PSTATE.UINJ is set, instruction execution at the
lower EL raises an Undefined Instruction exception (EC=0b000000).

This patch introduces support for FEAT_UINJ by updating the
inject_undef64() to use hardware undef injection if supported.

feat(build): enable link-time optimization by default

Enable LTO by default for all platforms and compilers. LTO performs
optimisation at link-time rather than at compilation time, and allows
optimisations to be made across compilation unit boundaries (i.e. C
files). This is especially useful in areas with lots of closely related
compilation units that operate on the same data structures (eg PSCI and
context management).

The only drawback is that LTO makes conditions ripe for the build to
heavily mangle all functions, making debugging a nightmare. So only
enable for release builds.

Note this will make object files unintepretable by objdump. Use lto-dump
instead.

BREAKING-CHANGE: LTO has been enabled by default, which may cause
unpredictable issues for platforms where the linker scripts have not
been designed with LTO in mind. Please report any issues to the
[mailing list](mailto:tf-a@lists.trustedfirmware.org).
