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).

feat(cpufeat): add support for FEAT_IDTE3

This patch adds support for FEAT_IDTE3, which introduces support
for handling the trapping of Group 3 and Group 5 (only GMID_EL1)
registers to EL3 (unless trapped to EL2). IDTE3 allows EL3 to
modify the view of ID registers for lower ELs, and this capability
is used to disable fields of ID registers tied to disabled features.

The ID registers are initially read as-is and stored in context.
Then, based on the feature enablement status for each world, if a
particular feature is disabled, its corresponding field in the
cached ID register is set to Res0. When lower ELs attempt to read
an ID register, the cached ID register value is returned. This
allows EL3 to prevent lower ELs from accessing feature-specific
system registers that are disabled in EL3, even though the hardware
implements them.

The emulated ID register values are stored primarily in per-world
context, except for certain debug-related ID registers such as
ID_AA64DFR0_EL1 and ID_AA64DFR1_EL1, which are stored in the
cpu_data and are unique to each PE. This is done to support feature
asymmetry that is commonly seen in debug features.

FEAT_IDTE3 traps all Group 3 ID registers in the range
op0 == 3, op1 == 0, CRn == 0, CRm == {2–7}, op2 == {0–7} and the
Group 5 GMID_EL1 register. However, only a handful of ID registers
contain fields used to detect features enabled in EL3. Hence, we
only cache those ID registers, while the rest are transparently
returned as is to the lower EL.

This patch updates the CREATE_FEATURE_FUNCS macro to generate
update_feat_xyz_idreg_field() functions that disable ID register
fields on a per-feature basis. The enabled_worlds scope is used to
disable ID register fields for security states where the feature is
not enabled.

This EXPERIMENTAL feature is controlled by the ENABLE_FEAT_IDTE3
build flag and is currently disabled by default.
