This adapts most of ccgstmts to cbuilder, missing C++ exceptions and
`genCaseGeneric`/`genIfForCaseUntil`. Rebased version of #24399 which
was split into some other PRs and since has had conflicts with #24416.
Not all uses of switch statements are implemented, `genCaseGeneric` and
`genIfForCaseUntil` still exist. The main purpose is to finish
`ccgreset` and `ccgtrav`.
Finishes `genEnumInfo` as followup to #24351. As #24381 mentions this
covers every use of `for` loops in the codegen.

follows up #24381
This is about another 30% of ccgexprs (remaining is up to around line
3000), stopped right before the point where #24391 is required.
The `Genode::log` and `Genode::Cstring` calls in `genEcho` are left as
is but could be mangled in the future.
C++ member procs are not implemented, and `codegenDecl` in general is
also not adapted, although it had to be included in the generation of
proc params for simplicity. Guessing `codegenDecl` and C++ stuff are
supposed to map to pragmas on NIFC, or are just not supported.
Most of what ccgexprs uses is now ported to cbuilder, so this PR makes
around ~25% of ccgexprs use it, along with adding `if` stmts (no
`while`/`switch` and `for` which is only used as `for (tmp = a; tmp < b;
tmp++)`). The `if` builder does not add indents for blocks since we
can't make `Builder` an object yet rather than an alias to `string`,
this will likely be one of the last refactors.
Somewhat unrelated but `ccgtypes` is not ready yet because proc
signatures are not implemented.
This PR is somewhat large, worst case it can be split into one with just
assignments and one with just fields/derefs etc.
Assignments with calls as values have not been touched so they can be
done when calls are implemented. Similarly codegen with complex logic
i.e. `genEnumInfo`, `genTypeInfoV2`, `unaryExpr` is not completely
ported yet so they can be done in standalone PRs.
