fix(dsp): drop INLINE from DSPExec to fix MSVC link error

DSPExec is declared in dsp.h with external linkage but was defined
INLINE (which expands to MSVC's _inline) in dsp.c. At v2.2.0 the
function was small enough that MSVC always inlined it, so no external
symbol was needed. Recent DSP changes (computed-goto, inline switch
dispatch, delay-slot inlining) inflated the function past MSVC's
inline budget — MSVC then emits the body with internal linkage only,
which causes 'unresolved external symbol _DSPExec' in jaguar.c at
Windows link time.

GPUExec (the parallel function in src/tom/gpu.c) is correctly defined
without INLINE for the same reason. Match that.

Also update RELEASE_NOTES_v2.3.0.md commit/file/line counts to match
the current branch tip (158 commits / 263 files).
