glint binary (which is basically tsc) does not implement support for glint-expect-error directives

From @johanrd from Discord

I see that VS code correctly ignores any line following@glint-expect-error, but the output of pnpm glintdoes not ignore them. Expected?

I checked with Vue/Volar team, apparently this is a known issue. I will need to take another pass at glint-expect-error to implement its filtering logic more within the VirtualCode implementation (which runs in all contexts including runTsc) as opposed to only in TS Plugin.

i was also running into this issue by using {{! @glint-ignore }}.
