cabal install does not accept relative dirs in --store-dir (but cabal build does)

[jneira]

Describe the bug
You can use relative dirs in --store-dir for cabal build but no for cabal install

To Reproduce
Steps to reproduce the behavior:

$ cabal --store-dir=./relative v2-install 

actual log

D:\ws\haskell\cabal-test>cabal --store-dir .\sr install --builddir dist2
Wrote tarball sdist to
D:\ws\haskell\cabal-test\dist2\sdist\cabal-test-0.1.0.0.tar.gz
Resolving dependencies...
Build profile: -w ghc-8.6.5 -O1
In order, the following will be built (use -v for more details):
 - say-0.1.0.1 (lib) (requires build)
 - cabal-test-0.1.0.0 (lib) (requires build)
 - cabal-test-0.1.0.0 (exe:cabal-test) (requires build)
Configuring library for say-0.1.0.1..
cabal-3.6.2.0.exe: expected an absolute directory name for --prefix:
.\sr\ghc-8.6.5\say-0.1.0.1-f56dd8dcb828e676e2fe979752cedce7d5e3ea47

Expected behavior
cabal install should accept relative dirs in --store-dir like cabal build

System information

• windows
• cabal-3.6.2.0, ghc versions: any

Additional context

Looks like I duplicated your issue in #7812.
