Update patch for db-5.3.
Minor cleanups.

devtools 20230105-1 enables the debug option by default.

archlinux/devtools!109 (comment 74475)

Remove unneeded quotes and curly braces.
Remove option to disable build of example-tools (off by default now).

Remove unrequired zita-ajbridge from optdepends (zalsa in jack-example-tools can be used).
Remove replaces array for jack2, as we do not want to remove jack automatically.

Disable LTO, as it leads to runtime crashes:
https://github.com/jackaudio/jack2/issues/485

Simplify splitting out of jack2-dbus.
Add jack2-docs to provide optional developer documentation.
Do not build/install libraries/executables provided by jack-example-tools.
Add jack-example-tools and jack2-docs as new optdepends for jack2.
Remove all depends/makedepends that were only required for jack-example-tools.

Add jack to replaces array, so that existing installations are replaced.
