Revert "[fuchsia] Pass switches by process type"

This reverts commit 1fba93c2f3.

Reason for revert: Possible culprit for Fuchsia builders:
https://ci.chromium.org/p/chromium/builders/ci/Fuchsia%20ARM64/132538
https://ci.chromium.org/p/chromium/builders/ci/Fuchsia%20x64/78606

BUG: 1336067


Original change's description:
> [fuchsia] Pass switches by process type
>
> WebEngineContentBrowserClient::AppendExtraCommandLineSwitches() copied
> kSwitchesToCopy to the command line regardless of the process type.
>
> Therefore, this CL passes switches based on the process type, depending
> on whether it is a renderer process, a GPU process, or a network
> process. This is very similar to what
> ChromeContentBrowserClient::AppendExtraCommandLineSwitches() does.
>
> Also, the kMaxDecodedImageSizeMb switch was removed because it is passed
> by content.
>
