Move the CompileWithBaseline interface to the Compiler class, as
CompileBaseline, which will do the additional work of pre-compiling
to bytecode, ensuring there is a feedback vector, and setting the
code on the function closure.
As a drive-by, fix v8_enable_trace_unoptimized to have a blank default
value, so that v8_enable_trace_ignition/v8_enable_trace_baseline_exec
can set it.

- Baseline is to be consider non-optimized code, so for consistency we rename these functions to DiscardBaselineCode.
- Move to debug/, since discarding baseline code is only used by the debugger.
- %DeoptimizeNow and %DeoptimizeFunction are not to be used to tier down from Sparkplug to Ignition

Currently we sometimes refer to baseline code or the baseline compiler
by its codename (Sparkplug). The codename is fun, but we should be
consistent and call things by one name or the other. Following the
pattern of Ignition stuff being called "interpreter", we call Sparkplug
"baseline", and leave the codename only in flags and variants.

Sparkplug is a new baseline, non-optimising second-tier compiler,
designed to fit in the compiler trade-off space between Ignition and
TurboProp/TurboFan.
