[enhancements] add support for "-include foo.h" flag

[afm0901x]

Describe the bug GCC and Clang have a flag to include header file before the parsing step.

To Reproduce Clangd already aware of this flag, I got it working by manually injecting "-include foo.h" to arguments block in compile_commands.json:

...
"arguments": [
    "/usr/bin/gcc",
    "-I../include",
    "-I/usr/include/bar/bar-2",
    "-include../foo.h",
...

Expected behavior Bear to add -include flag to compile_commands.json.

Environment:

• OS name: Linux
• OS version: Arch Linux, Kernel 5.18.1
• OS architecture: x86_64
• Bear version: 3.0.19
• Bear install method: Arch Linux Official repo

Hey @afm0901x , this functionality is already implemented. You can remove or add flags to the compilation database entries.

Read the man citnames config file section to see how to set it up. This config can be passed to Bear as --config ....
