strings: added function to get string pointer from a string constant

[sajjanjyothi]

This function will be useful mostly during testing. When we want to pass a string pointer to a struct member each time we have to create a separate variable and pass the address of that to the member variable, Which is a pain. This wrapper function will ease all those efforts.
Eg:
type Employee struct{
Name *string
}

To pass a variable in testing , we have to
testName := "hello"

emp := Employee{
Name: &testName,
}

With this function it is

emp: = Employee{
Name: strings.StringPointerFrom("hello")
}

It is really helpful when we are using table tests.

Patch Set 1:

Congratulations on opening your first change. Thank you for your contribution!

Next steps:
A maintainer will review your change and provide feedback. See
https://go.dev/doc/contribute#review for more info and tips to get your
patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be
surprising to people new to the project. The careful, iterative review process
is our way of helping mentor contributors and ensuring that their contributions
have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which
little code gets reviewed or merged. If a reviewer responds with a comment like
R=go1.11 or adds a tag like "wait-release", it means that this CL will be
reviewed as part of the next development cycle. See https://go.dev/s/release
for more details.
