This flag will force the usage of the mid-tier register allocator, which
is otherwise only used for huge functions, hence does not get much
fuzzer coverage.

Generic wasm wrappers are enabled by default now (since
https://crrev.com/c/2562241), so we can remove the flag from the
nooptimization variant. Instead, we should have a configuration which
tests --no-wasm-generic-wrapper to find bugs in the compiled wrappers
earlier.
Also add an entry for contradictory flags, and reformat that list to
respect the 80 columns limit.

This passes the --simulate-errors flag for differential fuzzing with
a probability of 0.01%.

Mostly gc-related flags didn't flush out any bugs yet, but often reduce
test performance and lead to timeouts.

Pass --no-lazy-feedback-allocation in all second runs depending
on a probability. Also combine with --interrupt-budget=100.
This also allows adding several extra flags behind one probability.
The tests are improved to ensure valid flags and configs.
