JIT: Don't set patchpoints in methods with CORINFO_DEBUG_CODE (#88227)

In #88199 the debugger is overriding some jit flags, but has left other flags set
that confuse the jit: both `TIER0` and `DEBUG_CODE` end uip set so one part of the jit
used logic appropriate for `TIER0` and another part did not.

The JIT ended up creating a patchpoint for OSR in a method with localloc and this
combination is not supported by OSR and lead to a crash.

Harden the jit so if the runtime asks for debuggable code, the jit will never
generate patchpoints.
