[committed] analyzer: mark epath_finder with DISABLE_COPY_AND_ASSIGN [PR99614]

[David Malcolm via Gcc-patches]

cppcheck warns that class epath_finder does dynamic memory allocation, but
is missing a copy constructor and operator=.

This class isn't meant to be copied or assigned, so mark it with
DISABLE_COPY_AND_ASSIGN.

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r11-7734-g21d09cb732dac5d980ac628eb3aca75c821028a2.
