Add CMake variable FISH_USE_SYSTEM_PCRE2 The CMake variable FISH_USE_SYSTEM_PCRE2 now controls whether fish uses system PCRE2 or the bundled version. The default is to use the system version, unless no such version is found, or unless it is a macOS build with code signing. Note the default behavior has not changed. Fixes #6952

# We can either use the system-installed PCRE or our bundled version.
# This is controlled by the cache variable FISH_USE_SYSTEM_PCRE2.
# Here we compute the default value for that variable.
Drop CMake PCRE2 download/linking and allow statically-linked PCRE2 crate pcre2-sys includes a vendored copy of PCRE2, which allows for statically-linked PCRE2. Hook this up to the CMake build variable, and remove the C++ integration for PCRE2.

# The actual decision is made by the Rust pcre2-sys crate, which searches for the
# pkg-config file and uses a vendored copy if it is not available.
