go/scanner: reject large line and column numbers in //line directives
Setting a large line or column number using a //line directive can cause
integer overflow even in small source files.
Limit line and column numbers in //line directives to 2^30-1, which
is small enough to avoid int32 overflow on all reasonbly-sized files.
For #59180
Fixes CVE-2023-24537
