Disable WebGPU for Firefox tests

Browse Source 
The GitHub Actions workflow for the integration tests on Windows logs
the following line for every test:

`JavaScript warning: http://127.0.0.1:62313/build/generic/build/pdf.mjs,
line 134934: WebGPU is disabled by blocklist.`

On Linux WebGPU is disabled by default because of missing support, but on
Windows it's enabled by default since bug 1972486, so we try to obtain a
GPU adapter which fails (and logs) if there is no actual GPU like on
GitHub Actions. Coverage data confirms that our own WebGPU code is
already uncovered because of the lack of a GPU, so having WebGPU enabled
or disabled doesn't change that, but if it causes log spam it seems
better to disable it, which this commit does.

Note that Chrome doesn't seem to have a matching flag, but Chrome already
doesn't log anything about this (which is the primary driver for this
change), so that's not a problem.
