dfda794f55 Add a custom section hook to ModuleEnvironment 
This commit adds a hook to the `ModuleEnvironment` trait to learn when a
custom section in a wasm file is read. This hook can in theory be used
to parse and handle custom sections as they appear in the wasm file
without having to re-iterate over the wasm file after cranelift has
already parsed the wasm file.

The `translate_module` function is now less strict in that it doesn't
require sections to be in a particular order, but it's figured that the
wasm file is already validated elsewhere to verify the section order.

e35cf861db Fixes #984: Add a isa::lookup_by_name function; 
This removes the explicit dependency on target-lexicon for the embedder,
which can instead use the ISA's name directly. It can simplify
dependency management, in particular avoid the need for synchronizing
the target-lexicon dependencies versions.

It also tweak the error when an ISA isn't built as part of Cranelift to
be a SupportDisabled error; this was dead code before this.

1a099f2e8c [codegen] change operand type from bool to iflag for isub borrow variants 
The type of the borrow operands for the borrow variants of the isub
instruction (isub_bin, isub_bout, isub_borrow) was bool for compatibility
reasons for isa/riscv. Since support for these instructions on RISC
architectures has been temporarily suspended, we can safely change the
type to iflags.

9fb8bdd6d5 [codegen] remove support for isub borrow variants on riscv 
Previously, the borrow variants of isub (isub_bin, isub_bout and
isub_borrow) were being legalized for isa/riscv since RISC architectures
lack a flags register.

This forced us to return and accept booleans for these operations, which
proved to be problematic and inconvenient, especially for x86.

This commit removes support for said statements and all dependent
statements for isa/riscv so that we can work on a better legalization
strategy in the future.
