[Flang] Add -fintrinsic-modules-path= alias (#149417)

Browse Source 
Add the syntax `-fintrinsic-modules-path=<dir>` as an alias to the
existing option `-fintrinsic-modules-path <dir>`. gfortran also supports
both alternatives.

This is particularly useful with CMake which de-duplicates command-line
options. For instance,
`-fintrinsic-modules-path /path/A -fintrinsic-modules-path /path/B`
is de-duplicated to
`-fintrinsic-modules-path /path/A /path/B`
since it conisiders the second `-fintrinsic-modules-path`
"redundant". This can be avoided using the syntax
`-fintrinsic-modules-path=/path/A -fintrinsic-modules-path=/path/B`.
