fix (remix-serve): fallback to default path if source maps aren't available when building stack trace

[VHall1]

Another update to source map loading. This should resolve issues where people reported getting server crashes when they had source maps disabled or when errors were being thrown by 3rd party packages (since source maps aren't available for those). All this does really is check that the file exists before loading it, and returning null if it doesn't (using the original path as a fallback). Mostly based on the patch suggested here: #8309 (comment)

Testing:

3rd party error (tiny-invariant)

generic error

generic error after manually deleting source map

Closes: #8309

yeah - since this changes source code, it should have a changeset. Would you mind pointing the PR to to dev as well?

[VHall1]

yep, sounds good to me! Will add the changeset and point to the correct branch later today.
