feat(test-ssr): add custom esbuild-plugin to properly resolve TS path aliases which stopped working starting esbuild 0.19

Previous Behavior

Esbuild stopped resolving TS path aliases since version 0.19 (BREAKING CHANGE)

https://github.com/evanw/esbuild/blob/main/CHANGELOG.md#0190 /

With this in place our SSR test are working by "accident" ( lage scheduling build task prior to executing test-ssr ), and following pipeline issues might start happening at any time (https://github.com/microsoft/fluentui/pull/29327).

This issue started to appear in one of PR's that removes a deprecated package from the repo https://github.com/microsoft/fluentui/pull/31007

New Behavior

this PR implements a custom ESbuild plugin to resolve against path aliases mittigating all the possible issues described above.
tested against whole repo https://github.com/microsoft/fluentui/pull/31220

More context

Even if we added build task as pre-requirement for test-ssr pipeline issues would appear sooner than later.

So we can either:

provide proper dependency declarations to all packages ( which would introduce circular dependencies - this will be mitigated after implementing https://github.com/microsoft/fluentui/issues/30516) + moving test-ssr to *-stories packages
implement tsConfigPathAliases esbuild plugin

Ideal solution is to have both so until that type-checking epic is done
