docs(cpufeat): clarify description of FEATURE_DETECTION macro

The current documentation of the FEATURE_DETECTION build option seems
to suggest that this macro enables the dynamic runtime checking of
features, although this is done regardless of this debug feature.
FEATURE_DETECTION just adds the detect_arch_features() function to the
build and calls it early on, plus it enables the CPU errata order
checking.

Simplify the description of the FEATURE_DETECTION macro to make this
clear, and move the dynamic feature detection description into a
separate section, before all the specific ENABLE_FEAT_xxx explanations.

This also renames all mentioning of:
"... to align with the FEATURE_DETECTIION mechanism ..."
with:
"... to align with the ENABLE_FEAT mechanism ..."
in the description of each feature.
