Fix clean build of simulator with `make sim`:
- Pass `TARGET=opt` instead of `TARGET=` when building tools
to ensure the tool gets properly built irrespective of environment
- Remove reference to obsolete Intel decimal library, which was still
hanging around in my build directories.

Reserve the main thread for display updates and keyboard interaction,
like for the Qt version. This allows the web simulator to work
correctly when you run a program or when you access the firwmare
interface.
The downside is that you need to run that on a web server that is able
to set the following [HTTP headers][coop]:
```
Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin
```
Unfortunately, it is not entirely clear if this can be made to work
easily with [GitHub pages][ghp].

This is an in-tree port of [Franco Trimboli's excellent work][wasm].
The goal is to be able to run the simulator in a browser.
This builds with emscripten, as installed by the `emsdk`.
The `emsdk` is added as a submodule, and initialized on first build.
To build the browser WASM version of the simulator, run `make wasm`.

With the original code, the loop searching for commands to add to the
catalog skips many commands. I suspect this is another case of QSPI
hammering similar to what was observed for fonts. In any case, the
workaround appears to be to slightly deoptimize the code by selecting
a lower optimization level and adding an `else` clause in the inner
`if` statement.

At some point, we will need to shift to variable-precision decimal.
Being able to disable all `decimal128` code will help evaluate
how much room we have for that.
With decimal128 active, sizes are:
text data bss dec hex filename
2254248 3840 2524 2260612 227e84 build/dm42/release/db48x.elf
wc -c db48x.pgm
710180 db48x.pgm
Without decimal128, sizes are:
text data bss dec hex filename
455864 2872 2412 461148 7095c build/dm42/release/db48x.elf
wc -c db48x.pgm
282236 db48x.pgm
In other words, decimal128 at the moment uses 427944 bytes out of our
716800 budget (i.e. 59.7%) and 1798384 in the total size (79.7%).
Chances that a variable decimal implementation can be made smaller
than that.

The `src/ignored_menus.csv` and `src/ignored_help.csv` indicate what

current state of missing things, and can serve as a reference for what

When the argument describing the variable is a text, interpret that as
a file path on the disk. By default, data is stored in in a directory
named `data`, which will be created if necessary. For example, you can
use `3 "foo.48s" STO` to store the value `3` in a file named
`data/foo.48s` on disk.
How the file is stored depends on the extension given to the file:
* For `.txt` files, the object is stored as text
* For `.48s` files, the object is stored as DB48X source code
* For `.48b` files, the object is stored in binary format
* For `.csv` files, the object is stored in comma-separated format.
The binary format used for `.48b` includes a 4-byte magic number
identifying a DB48X format, and a 4-byte checksum used to ensure
binary compatibility between the firmware and the disk format.
At least during early days of development (prior to 1.0), it is quite
unlikely that the binary format for one version of the firmware would
be readable or writable by another version. If you need to recover
data from another version, you need to install that version and save
the object again in `.48s` (text) format.
