Need a solution to load resource files from ballerina

[anuruddhal]

Description:
As per the current packerina design, we have the following data structure for a ballerina project.

├── Ballerina.toml
├── .ballerina
├── pkg_a
│   └── a.bal
├── pkg_b
│   └── b.bal
├── pkg_c
│   └── c.bal
├── resource
│   └──  hello.yaml
└── target

In order to read the resource/hello.yaml from a.bal we have to provide the absolute path of the file. This is not scalable.

We can't provide the relative path as the relative path is dependent on where ballerina run/build command is executed

Steps to reproduce:

Affected Versions:
0.980.1
