Extract properties file parser in a new project

[angelozerr]

LSP4MP provides a robust properties file parser which is:

• fault tolerant
• provides position ranges for property key and values.

This parser is used to provide support for application.properties and microprofile-config.properties (validation, completion, hover, definition, etc)

It would be very nice to extract this parser in a new project to give the capability to other projects to consume it:

• for Qute to manage validation, references etc in messages.properties (for Renarde) https://docs.quarkiverse.io/quarkus-renarde/dev/advanced.html#localisation
• for Liberty Tools Language Server https://github.com/OpenLiberty/liberty-language-server/tree/main/liberty-ls/src/main/java/io/openliberty/tools/langserver/model/propertiesfile
