This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.

This is similar in spirit to the work in 4d71a7913a
but for Windows.
This commit adds ANGLE binaries built from
07ea804e62
to the repo. The build and packaging will copy those into the same
directory as wezterm.exe so that they can be resolved at runtime.
By default, `prefer_egl = true`, which will cause the window
crate to first try to load an EGL implementation. If that fails,
or if `prefer_egl = false`, then the window crate will perform
the usual WGL initialization.
The practical effect of this change is that Direct3D11 is used for the
underlying render, which avoids problematic OpenGL drivers and means
that the process can survive graphics drivers being updated.
It may also increase the chances that the GPU will really be used
in an RDP session rather than the pessimised use of the software
renderer.
The one downside that I've noticed is that the resize behavior feels a
little janky in comparison to WGL (frames can render with mismatched
surface/window sizes which makes the window contents feel like they're
zooming/rippling slightly as the window is live resized). I think this
is specific to the ANGLE D3D implementation as EGL on other platforms
feels more solid.
I'm a little on the fence about making this the default; I think
it makes sense to prefer something that won't quit unexpectedly
while a software update is in progress, so that's a strong plus
in favor of EGL as the default, but I'm not sure how much the
resize wobble is going to set people off.
If you prefer WGL and are fine with the risk of a drive update
killing wezterm, then you can set this in your config:
```lua
return {
prefer_egl = false,
}
```

This is a bit of a switch-up, see this comment for more background:

This commit:
* Adds a pre-compiled mesa3d opengl32.dll replacement
* The mesa dll is deployed to `<appdir>/mesa/opengl32.dll` which by
default is ignored.
* When the frontend is set to `Software` then the `mesa` directory
is added to the dll search path, causing the llvmpipe renderer
to be enabled.
* The old software renderer implementation is available using the
`OldSoftware` frontend name
I'm not a huge fan of the subdirectory for the opengl32.dll, but
I couldn't get it to work under a different dll name; the code
thought that everything was initialized, but the window just rendered
a white rectangle.
Rather than scanning directories and reading in ~230 files on startup,
do the scan at build time so that we're parsing from memory rather
than local storage.
This should shave a bit of time off the startup, although I
haven't measured this, and I've only run this on a remote
linux system thus far.

When installed by the installer, we add registry entries to configure
directory context entries in explorer.exe that enable "Open WezTerm
here" to function.
This works by running your default program with the current working
directory set to the one specified.
I plan to only enable this when installed by the installer so that
these can be deleted/updated by the installer later on.
If you want wezterm to run a different program by default, then
you can change the default_prog config in the wezterm configuration;
I don't plan on adding lot of context menu entries for this.
Note that attempting to open in the `C:\` root doesn't always seem
to work for me. I haven't had a chance to understand what's going
on there.
