src: fix crash in GetErrorSource() for invalid using syntax

[semimikoh]

Fixes: #62767

V8 can report an invalid source range for some malformed using and
await using declarations, with the end column preceding the start
column. GetErrorSource() currently asserts that the end column is
greater than or equal to the start column before reaching the existing
bounds check, so formatting the SyntaxError aborts the process.

Remove the assertion and only apply the script start offset when both
columns can be adjusted. Invalid ranges now fall through to the existing
fallback path, which prints the error source without an underline instead
of crashing.

Add regression coverage for the four invalid using / await using
cases reported from test262.
