exec: Rename NEED_CPU_H -> COMPILING_PER_TARGET

'NEED_CPU_H' guard target-specific code; it is defined by meson
altogether with the 'CONFIG_TARGET' definition. Rename NEED_CPU_H
as COMPILING_PER_TARGET to clarify its meaning.

Mechanical change running:

 $ sed -i s/NEED_CPU_H/COMPILING_PER_TARGET/g $(git grep -l NEED_CPU_H)

then manually add a /* COMPILING_PER_TARGET */ comment
after the '#endif' when the block is large.
