[error messages, stacktraces] fix #8794 #9270 #9767 #9768 (#9766)

* fixes #8794 : `Error: undeclared field: 'foo'` should show type (+ where type is defined) (hard to guess in generic code)

* fixes #9270: `--listFullPaths` not honored by `declared in foo.nim` messages

* fixes #9767: VM stacktrace doesn't honor --excessiveStackTrace:on

* fixes #9768: VM stacktrace misses column info, can lead to ambiguous or harder to read stacktraces

* refactors some col+1 code to col + ColOffset (self documents code)

* make getProcHeader show declared info location also for types and all routine kinds (including macros,templates) instead of just (rather arbitrarily) for iterator,proc,func,method

* --listFullPaths now is honored in more places

* fix typo system/except.nim => lib/system/excpt.nim

* remove substr(foo, 0) hack in compiler/vm.nim which seems old and not applicable anymore

compiler/semcall.nim
