Disable inlay hints (in .clangd project config) by default (IEP-1260)

[powerbroker]

LSP Editor, used for C/C++ files of ESP-IDF project shows inlay hints, e.g. parameter names in function invocations.

looks and behaves suxy: they appears with a delay, they reside within editor area but are NOT EDITABLE and they VIOLATE language syntax.

moreover, there is no option to prohibit such annoying staff in Eclipse settings. the only way to get rid of them is '.clang' file in project root or 'config.yaml' in user home folder - https://clangd.llvm.org/config#files.
since affecting global level through user home is bad idea, the

InlayHints:
Enabled: No

inside project's '.clangd' file is a lifesaver.

To Reproduce
just open C/C++ file with some function call in LSP Editor of Eclipse.
enjoy appearing of parameter names before parameters in function invocations and in places like them after some delay.

Expected behavior
all-the-text within editor area is fully editable. no syntax-breaking (even visually) inline constructs appear: what-you-see-is-what-you(=compiler)-get.
everyone who needs this feature may ENABLE it, e.g. somewhere in Eclipse preferences.

Screenshots

note separate area for line numbers on the left and for color markers on the right - each one for different kinds of hints. it would be logically correct to place such hints within e.g. tooltips, but never inside text editing area.

YES! This has been infuriating me since it was introduced. It's an awful feature and I'm boggled there's no UI preference to disable this - so THANK YOU for explaining how to at least hack the .clangd file and get rid of this.

+1 for disable by default.

Also thanks for the hint on how to disable, uh, hints.
