[WIP] build: name install targets as components #31847

   Adds component names to the CMake install targets to allow for component-based installs. Such installs are helpful when a user only wants to install bitcoind or bitcoin-cli executables specifically, for example.

   At present, the component names use Pascal case to follow the existing convention for the only pre-existing named component Kernel, however, there is a convincing case to be made for using kebab-case to more intuitively match the names of the executable binaries.

   Component based installs can be performed using:

   0cmake -B build
   1cmake --build build --target bitcoind bitcoin-cli
   2cmake --install build --component BitcoinD BitcoinCli
   

   Supported targets:

   • BitcoinWallet
   • BitcoinD
   • BitcoinNode
   • BitcoinCli
   • BitcoinTx
   • BitcoinUtil

   Attempts to close #31745.

   Possible improvements:

   • Scour other nested CMakeLists.txt files for additional targets.
   • Switch to kebab-case

   New contributor here; new to Bitcoin, new to CMake, happy to help, learn and receive feedback.

   Currently submitted as a draft to inspect build results as a PoC.
