patch 9.0.1835: Perl interface has problems with load PL_current_context
Problem: Perl interface has problems with load PL_current_context
Solution: Fix Perl interface to load PL_current_context from library
In #12914, in order to fix an issue with Perl 5.36 dynamic builds, (that
version introduced a thread-local `PL_current_context`), the file added
the variable manually so we can satisfy the linker. However, the
variable is a different one from the one in the library, so there could
be unpredictable behavior. Instead, just use `dlsym` to load the context
from the library. The fact that it's thread-local doesn't matter too
much to us because Vim's interface is single-threaded so it will work
properly.
closes: #12996
