[hipblaslt] upload coverage reports to codecov.io (#1945)

## Motivation

Preparing hipblaslt for uploading codecov.io reports to codecov.io

## Technical Details

Added a command to convert llvm-cov (profdata) format to lcov format for
upload to codecov.io.

Also adding a hipblaslt codecov job in CI and had to fix the code cov
process because test case code was being instrumented, which will result
in misleading coverage reports.

## Test Plan

Will prove that this runs in the newly created CI job. Comment should be
made on this PR about the projects coverage by codecov.io.

## Test Result
