#122171)

HostActivation tests are hitting the 5-minute hang dump timeout on OSX
CI despite making steady progress. Tests complete in ~2 minutes locally
but CI environments run 2x slower.

**Changes:**
- Increased `--hangdump-timeout` from `5m` to `8m` in
`src/installer/tests/Directory.Build.props`

This provides adequate headroom for slower CI machines while still
catching actual hangs.

This is the first prototype of a Wasm object writer for crossgen that
*only* writes out method bodies. It builds the minimum module structure
which is needed to declare and export the module bodies so that the
resulting module can be loaded and method bodies can be called by an
external loader. I have tested the output with a simple JavaScript
loader that instantiates the module and calls one of the exports.

# What IS handled
Emitting simple method bodies from an assembly that have no relocations
or external dependencies of any kind.

# What is NOT handled
## Relocations and any metadata attached to compiled methods.
## R2R format envelope (the plan is to embed this in the data section in
a future PR)
R2R metadata is currently unused.
## Signature generation to meet ABI requirements
Right now, there is a single `i32 -> i32` signature which is used as a
placeholder for any method. Later work will need to build support for
generating and storing wasm-level type signatures for JIT compiled
methods.
## JIT Integration
Currently, the JIT is not called (I believe it will hit asserts on the
Wasm target until #121973 is in). Instead, a simple `(i32.const 0)
(return)` stub is emitted for any JIT calls.
