* origin/topic/vern/CPP-streamlining:
BTest baseline updates for compile-to-C++
mark ZAM regression BTests as not suitable for compile-to-C++
fix for -O gen-C++ maintenance helper to skip BTest intermediary files
introduced simplified initialization for non-standalone -O gen-C++ code tied -O gen-standalone-C++ to use of --optimize-files
streamline generated -O C++ code by relying on per-function profiles rather than aggregate profile
when reporting available/unavailble C++ script bodies, flag those that are skipped
modified AST profiling to mark (and fully skip) non-optimizable functions
modified merge_types() to skip work if given identical types, which also preserves type names (useful for -O gen-C++)
* origin/topic/vern/script-opt-uncompilable-AST:
ScriptOpt: Fail compilation if known exprs/stmts is outdated
skip optimization of functions with AST nodes unknown to script optimization
Currently, plugins do not have a way to further inspect or even mutate
script functions after ZAM optimization ran. One use-case here is
zeek-perf-support [1]. This plugin wraps Stmt instances of functions,
events and hooks hooks with a small assembly stub to support JIT map
files [2] and for integration with perf tools.
This change introduces a new InitPreExecution() hook that runs after
ZAM optimization completed, just before the zeek_init() event is enqueued.
Additionally, remove the existing CPP_activation_hook. It doesn't seem
to be used. If it becomes necessary in the future, the new
InitPreExecution() hook can be leveraged instead.

This largely copies over Spicy's `.clang-format` configuration file. The
one place where we deviate is header include order since Zeek depends on
headers being included in a certain order.
